The Jungle is the first of four worlds in Mekabolt. However, it is technically only one of two required. As previously stated, we only need to beat 48 of the 96 levels in the game, and each world has 24. Therefore beating only the first two worlds is the easiest, and most time efficient way to earn all of the achievements.
Also, if you prefer a video guide, BiLLzuMaNaTi has created a full video walkthrough of the 48 levels you need to play:
Head into the first level to be greeted with some backstory explaining the robots and the batteries, hit to continue past each of the slides.
When you actually load into the level, jump over the first set of spikes. In the tunnel ahead, there are two sets of spikes on the ground which, if you run past, will not hurt you. Jump over the second set of spikes and walk into the battery to finish off the first level.
Jump across the spikes to the wooden platform ahead. Like in the previous level, in the tunnel ahead, there is a single hidden set of spikes. Again, run past them in order to not get hurt. When you reach the edge, you may notice a weird yellow cupcake sprinting back and forth. This is what I like to refer to as a block robot. These guys are quite useful. Simply hop down and shoot it before it touches you. This will stun him, allowing you to push him. Push him against the wall, and hop up a few times to grab the battery.
As soon as you load into the level you will receive:
and you should be able to see the flying robot in front of you. When you shoot a flying robot, they will be stunned and then drop to the ground. Then, when you jump on top of them, they will become unstunned and will restart their path that they were moving on before you stunned them. They are useful to reach areas up high.
For this level, jump up the platform and shoot the flying robot ahead of you. Once it is stunned, hop down, but watch out for the hidden spikes in the corner closest to you. Jump on top of the flying robot, then when it's at its peak, jump to the platform to the right. Continue jumping to the right until you reach the final platform, which has the battery located on it.
Like the previous level, as soon as you load in, you will unlock:
Jump over the spikes in front of you, and continue to walk down further underground. When you reach the bottom, be mindful of the three hidden spikes located on each of the three different platforms ahead. After passing the third hidden spikes, you should see a new robot friend in front of you.
These are the bouncy robots and they act very similarly to the block robots from the first level. When you shoot them, they will become stunned and you will be able to push them. Jumping on top of their heads gives you a boost to reach higher places. I will note here that if you somehow get a robot into a position that they can no longer be pushed in the direction you need them to go (for instance, pushing this bouncy robot all the way against the right wall), shooting them again will unstun them.
So, stun the bouncy robot and push it in between the first and second spike that is hanging above. Jump on it and move to the platform that is holding the first spike. Jump across the platforms to the right and then to the wooden platform above and to the left. Jump through the tunnel that contains a hidden spike in the ground and grab the battery.
From your starting position, shoot the flying robot. Jump on it and then quickly jump off to the right before you run into the spikes above. To your right will be a block robot, shoot it and push it as far right as you can. Jump on it, jump to the platform to your right, then up to the wooden platform and walk left to the battery.
Shoot the bouncy robot to the right, and jump over to its platform. Push it as far right as you can, then jump over it and hold right. This will make sure you land safely on the platform above. Shoot the two flying robots to the right, then jump onto the first one and quickly jump to the second, as if you stay on the first one for too long, it will kill you. From the second flying robot, jump to the platform to the right at its apex to get to the platform with the battery on it.
At the beginning, you can only shoot the first three flying robots, do so then quickly jump over to the third one, as you are safe on this one. From this one, shoot the last one and jump onto it as well. At the peak of its path, jump onto the platform to the right. Fall onto the small wooden platform below, then jump over the spike pit. Then jump up the blocks to the right and up to the wooden platform for the battery.
Shoot the first bouncy robot and push it as far right as it can go. Bounce on it to the wooden platform above. Do the exact same with the next bouncy robot to get to the top wooden platform. From here, run and jump over the two hidden spikes to the right to land on a single platform below. Jump from this platform to the final one which has the battery on it.
For booting up the ninth level:
and you should see the shooter robot up and to the left. These robots will constantly shoot yellow bombs along the ground. If they hit you, you will have to restart the level. If the bombs hit leaf blocks, like the ones to your direct left, the leaves will catch on fire and open up a path to you. Unlike the other robots, you cannot stun the shooter robot. Instead, when you shoot them, they will switch direction.
Wait until the leaf blocks have burned, then quickly jump up the rocky platforms to your left, dodging the bombs and shooting the shooter robot at the top to switch its direction. This will cause the leaves on the left to burn, allowing you to jump over the shooter robot and the hidden spike pit below to the next set of platforms. Jump up the platforms to get the battery for the level.
Jump up over the leaf block onto the platform to the right. Drop down from here to see a bouncy robot and the occasional bomb drop from the shooter robot up above. Shoot the bouncy robot and push him to the far right. Just as a bomb passes, quickly jump on top of the bouncy robot to a platform on the right. From here, jump a single platform to the left and shoot the shooter robot once. It might be a little hard to time, but you should be able to do it. Once it drops at least one bomb to the left, jump up to the platform with the shooter robot. Shoot the shooter robot again, then quickly jump over it back down the platform that we first jumped to. Drop down, jump over the hidden spike pit, and grab the battery.
To your left will be a stone staircase of sorts with a shooter robot dropping bombs down it. Maneuver over the bombs, then quickly shoot the shooter robot when you get to the top so it faces the wall and no longer shoots. Using the shooter robot as a platform, jump up to the wooden platform above. Now to the right will be a spike pit with a shooter robot shooting bombs down a staircase. Carefully time the jump over the pit and up the next few jumps to the shooter robot. Shoot him to switch its direction, wait until it burns the leaf blocks down, then shoot it again so it is facing the original direction. Hop down the pit, being careful of the hidden spike underneath the single block platform, and grab the battery.
To your right will be a spike pit, with bombs coming toward you. Dropdown a single platform, so you are one 'block' above and to the left of the spikes. Like the last level, carefully time the jump to cross the pit as to not hit the bombs. Jump up to the next platform, but do not go too far to the right, as you will be hit with bombs dropping in from above. This shot may take a few attempts, as it can be a bit tricky. Continue to dodge the bombs from the right and shoot the shooter robot. It will switch direction and burn the leaves right next to it. Jump up to its platform, minding the bombs coming down from above, and once it burns down the leaves switch its direction back to the left and hop over it. Jump onto the single platform with the spikes pointing down, making sure not to fall down to the right, as there is a hidden spike trap here. Shoot the flying robot to the right by jumping and shooting when it floats down. When it reaches the top, jump off to a single wooden platform to the right. Jump across to the big platform to the big wooden platform on the left. At the end fo the platform, hold left to fall down to a floating platform with two sets of spikes on it. From here, jump up and shoot the shooter robot to the left, allowing you to make the jump and burn down the final set of leaves. Jump up right next to the shooter robot, then quickly shoot it back to its original position and jump over it. Jump up to the last platform, being careful not to fall off the edge all the way to the left and having to restart the level, and grab the battery for two achievements:
For booting up this level and encountering a new enemy:
Run right, timing it so you aren't crushed by the giant fist slamming into the ground. Shoot the flying robot to stun it. Jump on it and at the top jump off to the left where you will see the new enemy: spear throwing robot.
These guys will shoot a spear out in both directions when you shoot it. These spears can kill you, so make sure to avoid them. The spears will also stick into walls, giving you a new way to climb up. After shooting their spears, the robots cannot harm you.
Once you make it to the platform, jump and shoot the spear-throwing robot. By the time you land back down, the spears should pass overhead, dodging you. Once they have lodged in their respective walls, ignore the one on the right, then hop over the spear-throwing robot. You will see the left spear has stuck itself into a wall above a spike pit. Jump onto the handle of the spear, then jump to the left again, minding the spike above you and the double hidden spikes in the ground in the platform to which you are jumping to. Once you make it on the platform, simply run to the battery.
Shoot the bouncy robot to your right and push it all the way to the wall. Jump on its head to a wooden platform with a spear-throwing robot to your left. Walk all the way to the right wall then shoot the spear-throwing robot, making sure to jump before the spear hits you. Use the handle of the spear to jump up to the platform to the right, then jump to the wooden platform to your left. Jump up to the big platform, then fall off the edge to the left to land on the other spear handle. Jump up another platform to your left, then fall onto the wooden platform below you. Simply walk off this platform and continue holding to make it to the other side, then jump up to reach the battery.
Shoot the block robot below you and push it all the way against the right wall. Jump on it and then up another platform so you are right next to the flying robot. Shoot the flying robot then jump on it. When you get to the top, jump onto the spear-throwing robot and over to its right, making sure you shoot the block robot as soon as you land, so it does not kill you. From here, jump on top of the block robot and shoot the spear-throwing robot to your left, making sure to dodge the spear as it gets thrown at you. Push the block robot under the spear and then jump onto the spear itself. Now, in a quick motion, jump, shoot the spear-throwing robot to your right, then fall off the spear you are standing on to the left, back onto the platform below. From here, quickly unstun the block robot, and then shoot it again once it has moved away from the wall. Push it as far left as you can, then jump on it and then onto the spear-throwing robot. Jump back onto the flying robot, and then to the spear staircase to the left. Climb up both of the spears, over the platform, and grab the battery.
Jump up to the platform on your right. Facing left, shoot the spear-throwing robot and quickly jump over its spear. Jump onto the handle of the spear, then to the wooden platform to the left. Again, shoot the spear-throwing robot, and jump over its spear. Jump onto the spear handle from this robot and then up to the grey platform to the right. Walk all the way to the right edge, and you should see a shooter robot in the top right-hand corner. From the edge, quickly jump, move right and shoot the shooter robot up here, making sure not to land on the hidden spike traps on each of the platforms below. Jump down to the last of the three platforms, just above the second shooter robot, and time it so that you drop down when there is not a bomb, then shoot the shooter robot so it turns and burns the leaves to the right. Once it has burned the leaves, quickly shoot it again and jump over it and fall down to the area below. Ahead is a double hidden spike trip, so quickly dodge it and jump onto the grey block right next to the fist. Time it right and run under the first fist, wait on the platform, then run under the second fist into the battery to end the level.
Shortly after starting this level up, you should unlock:
and you should be able to see two of the bomb dropper robots at the top of your screen. These robots are similar to the shooter robots as they also shoot bombs, except they will shoot them down (and sometimes up) and in an easily seen pattern that tends to be two bombs and then a gap where you can run. Dodging them is not too difficult, just see the pattern a few times and take your time.
Jump up to the grassy platform to your right, and drop to the wooden platform below you. Time the first bomb dropper robot and run to the grassy safe haven in between the first two. Do the same again with the next two bomb droppers. After the last bomb dropper robot, simply run off the end of the wooden platform. Be careful here, as the bombs will go through the wooden platforms. Walk all the way down, dodging the third bomb dropper robot's bombs. Shoot the bouncy robot down here, push it all the way to the left wall, and bounce on its head to the grassy platform to the left. Dodge the first bomb dropper robot's bombs and grab the battery.
Fall down to the left, making sure to jump over the spike pit below. No different than before, dodge the fist that is punching down and jump over the spike right next to it. Dodge the bomb dropper robot's bombs and take shelter under the single grassy platform with the spike on top. Dodge the second set of bombs, then fall off the left edge of the platform. Jump over the pit that contains a hidden spike trap, but do not walk too far as the first bomb dropper robot's bombs can reach here. Dodge the bombs again and fall down to the set of platforms with the spear-throwing robot. Quickly shoot it and jump over the spear to not get hit. Jump over the spear-throwing robot, then make sure to quickly fall into the pit and then jump out as to not get hit by the hidden spikes. Jump onto the spear handle and jump onto the platform with the battery.
Jump right to the only platform you can at the moment, and then dodge the bomb dropper robot's bombs and run as far right as you can. Jump into this tunnel being mindful of the spikes above you and land back down on the wooden platform on the other side. Jump up slightly onto the grey block to your right, and fall down and run right when you can dodge the bombs. Turn left, shoot the spear-throwing robot, and jump over the spear. Jump onto the handle of the spear to your right, then shoot the bouncy robot when it is either directly under the wooden platform closer to the right wall, or when it is to the left of that platform, but with enough room for you to jump up to that platform. It is not possible to get to its right side with the spikes on the roof, so you have to get it right under the platform or push it from the left. When it is lined up under the wooden platform, jump on its head and go on up.
Here is where we have the first instance of the bomb dropper robots flipping direction. These robots will flip to face the direction that you are on. So if you are on the path above them, they will shoot up, and vice versa.
Simply dodge the bombs again, making sure to quickly cross both of the hidden spike traps in the tunnel. Dodge one more set of bombs and grab the battery at the end.
From your starting platform, shoot the bouncy robot to your right, and cross over to its platform. Push it as far right as it can go and bounce on its head. When you are in the air, you should see a spear-throwing robot to your left. In the air, you need to shoot this, and then make sure you do NOT fall back onto the bouncy robot's head, as the timing will put you right back into the spear's path. So after you shoot the spear-throwing robot, move left in the air as to not land back on the bouncy robot. Once the spears have stuck, jump back on the bouncy robot and move to the right, where one of the spears has stuck. Jump up the spear handle and up another platform to a large grey platform that has a bomb dropper robot. Simply dodge the bombs, and then dodge another set of bombs from a bomb dropper robot below. Right after the second set of bombs is the battery for this level.
Jump up onto the wooden platform, and then shoot the shooter robot so that it faces the wall to the right. Jump up to its platform, and make sure to jump over the hidden spike trap, onto the shooter robot's head. Jump onto the grassy platform and over the spike pit to another grassy area that has a hidden spike trap in the middle. Run over it quickly and jump over another spike pit. From here, jump up to the large wooden platform and make simple jumps to the left, then down once to end up right next to a flying robot. Shoot the flying robot and drop on to its head. At its apex, jump off to the highest platform on the right. Walk across this wooden platform and make one more jump into the battery.
For this level, you need to first time the bombs to drop down onto the platform where they are being shot, then quickly move to the wooden platform to the right. Continue to drop down, and shoot the bouncy robot when down here. Push it all the way to the right and jump on its head and land up and to the right. Facing left, there will be a spear-throwing robot. Like usual, jump and shoot it, which should allow you to dodge the spear. Once you have shot it, time the bombs from the second bomb dropper, and jump on top of the spear-throwing robot. Jump up onto the wooden platform, and make one more jump which should make the bomb dropper robot to your left flip direction and burn the leaves. From here, head all the way back to the start by going back the way you came, making sure to dodge the bombs, and move the bouncy robot to the far left. Once you make it back to the first set of bombs, time your jump as to land onto the platform, then onto the spear. Jump up one more platform and continue left for the battery.
Jump up to the platforms on your left, timing it so that you don't get hit with a bomb. Once you are on the platform with the spear-throwing robot, shoot it and jump over the spear. From here, look right to see the shooter robot. From this position, shoot it, and it will burn down the leaves below. Jump onto the spear, and then onto the platform with the shooter robot. Shoot the robot once again, and quickly jump on its head. While avoiding its bombs, jump to the small wooden platform on your right, fall to the platform below, then fall down to another platform. From here, jump to the single platform to your right and quickly jump again to not get hit with the hidden spike trap. Fall down one more time and collect the battery.
Fall down to the right, and continue to under the wooden platforms when the bombs are not falling. Jump up the wooden platforms to the very top where you will see a spear-throwing robot to your left. Shoot it and dodge the spears. When the timing is right, jump to the wooden platform right next to the spear-throwing robot, then jump on top of the robot and fall to the platform to its left. Make the jump to the other wooden platform to the left, then move the second one when the bombs will not kill you. Jump onto the spear in the left wall, then over the grassy platform. Fall down and grab the final battery of this world, which will net you:
Onto the second world, The Desert!
