Overall, this game is pretty good. Its best parts are its visuals (mainly lighting) and sound design. I see that this is inspired from "Escape" from Ben's unreal course. The puzzles are alright, but I would say that the worst part is going back to the start every time you die. It makes the game too frustrating, considering that it is supposed to be a puzzle and not a platformer. I would try to make the file smaller, but it may not be possible. I would also say that it could some easier levels, but I can understand if you didn't have the time for that. Still, this is a pretty solid game.
