i have managed to somehow go and walk on top of the walls. (edit: it involves bush. also the bushclip is OP, it can litteraly solve puzzles fast) (edit2: i forgot to mention the bush has to be done near a wall, as well the bush acts like a wall and if you can walk on the bush, the game lets you walk on walls and also that box thingy with gravity)
i beat the game! (note:it reset)
