Walk forward to the archway and interact with the syringe on the ground, to the right of the column. Head through the archway, towards the stairs and interact with the blood stain on the floor as well as the gun, before heading to the camp on the left. Interact with the notes pinned to the hanging cloth and open the box to the left to the tent for a letter to open the sanctuary. Head back to the stairs, and facing them, go to the right and you should see a mural you can go and inspect. Keep heading to the right to find another camp, and in a box on top of a crate you can find a picture of Harry sleeping, creepy. Head up the nearby stairs and interact with the fish head statue, then return to the archway and interact with the column here to open the door and unlock:
Head through the door and scattered on the exterior of the room are four different constellations you need to interact with as well as another mural at the back of the room. In the centre of the room, head down the steps and interact with the pentagram shaped symbol. Head back up the steps to the entrance and you'll see two raised platforms with buttons you can activate on the left and ride side, which cause stones to roll out. Refer to the images provided below to open the constellation doors.
You will need to use the first picture for the first number to figure out which rock to interact with. Then you need to look at the second picture to figure out which symbol on that rock to press in order to open the constellation doors. The first door to open is 1-4 and 3-4 (so rock 1 and symbol 4, then rock 3 and symbol 4) and the constellation door on the right will open. Go through the door and interact with the mural on the right, before continuing on up the stairs to find another fish statue to interact with to get another mark.
Head back to the pentagram puzzle and clear the constellation if it is there by redoing the combo 1-4 and 3-4. Then do 1-5 and 4-5 to open the next door on the left. Head through the door, but be sure to interact with the mural before going up the stairs and interacting with another fish statue. Then head back to the pentagram puzzle and clear the constellation.
The next door combination is 1-2, 3-2 and 4-4, then the other door on the left should open up. Head through the door and go down the stairs, interact with the mural on the left before going through the palm panel and swimming forward. Interact with another palm panel here and then interact with the fish statue ahead.
Head back to the puzzle pentagram and clear the constellation once again. The next door combination is 1-5, 2-4 and 3-5. Once you go through the door and go up the stairs to the right, you'll see the last mural in the game, unlocking:
Head back down the stairs and go towards the panel in front of the water, where you'll have to create a path forward. First you want to interact with the middle black diamond, so that the path indicator in front of you is facing towards you and to the right. Make sure the black diamond on the right makes the path indicator on the right pointed towards the middle path indicator. Then hit the gold button on the right. Refer to the image below for reference:
Head to the panel on the right, which controls the white path indicators. Interact with the left white diamond and look to the left, the path should be going left to right. Refer to the image below for reference:
Interact with the middle white diamond until the far back path indicator is facing you. Move the right white diamond until it is facing left and right and hit the golden button. Refer to the image below for reference:
Head back to the black path panel and interact with the middle diamond until it points towards you and to the left. Interact with the left black diamond until the far back left path indicator is pointing towards you and to the left. Refer to the image below for reference:
Follow the path to the alcove on the left where a postcard should be on the ground, interacting with it will unlock:
Head back to the black stone panel and interact with the left diamond until the path indicator is pointing towards you and to the right. Hit the gold button. Refer to the image below for reference:
Follow the path for another fish statue and then head back to the pentagram puzzle and clear the constellation. Put in 1-1 and 4-3, then interact with the new constellation in the sky to unlock:
Clear the constellation and put in 1-5, 2-1, 3-3 and 4-4. The last door will open, unlocking:
Move through the door and down the stairs, interacting with the black ooze in a stone looking picture frame. Continue forward and as you come into an open room, you should unlock:
Keep going down the rocks as they form to eventually reach the corpse in the chair. After a short cutscene, you'll unlock:
Go through the door and keep following the steps and path as you figure out what happened. Make a save at the end before you open the door if you want to see both endings. Enter the door and choose to accept your fate and leave Harry. Go through the door and walk forward until you see a ring around the path, head left on an invisible path right where the ring is (refer to the images below if you're having trouble finding the path:
Walk up the path and inspect the key to unlock:
Keep walking along the main path and you'll swim forward a bit to enter a current. Once you come out, just keep swimming forward to have the game fade to black and unlock:
One more thing to do before we're done with the game. Back at the main menu, select chapter selection and choose any chapter but the prologue, and as you load in you should unlock:
And that is your 1000G! Congratulations and thanks for using my walkthrough. Don't forget to reload your save if you want to watch the other ending!
