can someone explain how i go to the 2d thing on the wall im kinda stuck on the first room
So there is a sweet spot, you have to find and then you click the "F" button just sorta frame it so the square is in the middle. Easiest way is to put the puzzle in the middle of your screen, and walk backwards and you'll see the "F" prompt.
Most of the game is finding that sweet spot to then hit the "F" button :)
