Major credit to DuWease for their initial solution. The solution itself and the comments found on it were hugely influential in my experience completing this achievement and making this solution. I just wanted to build on everything and have something a bit more comprehensive for you all that can continue to grow since DuWease is no longer active on TA / Xbox. (See the Community Advice section)Oh boy... This achievement took me a while to complete, so let's get started!
First of all, the ship I would recommend is the Solar Dominion or the Storm Conductor. Personally, I succeeded with the Solar Dominion as the Bouncing Spread Shot helped an incredible amount.
And when it comes to general gameplay, collect as many fuel / battery cells as possible to earn points and power up your Gun Meter as fast as possible. Every 10000 points earned will result in you getting 1 life, and SO WILL COMPLETING A LEVEL!
Now let's talk about each level!
Level 1:
Nothing too insane to talk about with this level, but when it comes to the boss fight, stay below the "lip" of the boss using your Straight Shot (since it has splash damage) and then in between the Boss' attacks, go to the centre and shoot into it's "mouth". See
06:55 in the video to see what I mean.
Level 2:
The "caves" are REALLY ANNOYING. You can lose a ton of lives with simple mistakes, so I would highly recommend you learn the paths by playing this level individually and practicing so you are prepared. My rule of thumb: Straight Shot to be used in cramped areas, bouncing shot to be used in more open areas or when there are no enemies directly in front of you.
Once you make it through the "caves", you are going to be fighting the boss. This boss is fairly simple, but also quite difficult at times. Immediately when the boss shows up, spam your explosive straight shot in the centre of the screen on the right side. This damages the boss before they can even attack you!
If you're lucky, you can do a TON of damage really quick. After that, avoid the attacks while using the straight shot or bounce shot to damage the heads as much as possible, and try your best to avoid the laser. I died a ton on this boss when practicing, but with the above tips I beat this boss without dying once. See
10:49 in the video.
Level 3:
Quite a long level if you ask me! A much easier level to navigate than the second level, but there are plenty of areas where you can make a mistake! For the tesla, do your best to avoid the initial attacks and then once it starts moving and firing rapidly, rotate around the tesla coil to avoid damage quite easily (
12:50). When it comes to the soldier guy that shoots beams at you, get on his right side and you will be safe (see
13:35). And finally, when it comes to the boss, spam the bouncer shot and avoid the boss' attacks to the best of your ability. If you spam the bouncer shot that the Solar Dominion has, this boss will be defeated in a decent amount of time. Remember to use your flamethrower, but also take into account that if you drop below 75% on your gun meter, you will lose your power weapons!
Once the final boss is defeated, that is Lunar Lunatic unlocked! Hope I was able to help you with the video below and the information I have provided.

RNG for the first Boss mostly relies on where you are when fighting it. Generally, I stay below the lip on the bottom fire a couple shots then go back down. Staying down there seems to lessen the chance of it firing the big exploding orbs. I've had some games where it never fired them at all. At 11:05 you briefly trap yourself above the second boss, this can end a run if a tracker orb hits you up there. I swear to god some of the orbs are invisible. At 12:38 in the video, you risk losing a life by staying infront of the two ships that begin to fire at you. You can avoid all the risk here by flying into the gap between them.
Here is my video guide for those that may prefer one:
