Really good FPS which reminds me of another game - BoxLife. I am surprised because I found your game recently and I don't remember it when I participated at this 43rd LudumDare. The controller is a little bit too weird and I think that it could be improved. The main gameplay is clever and I can imagine how hard it was to correctly create the unique level without any way so as to break the rules. The main aesthetic is gorgeous. It deserves more ratings :) Thank you for this good game. I wish you the best ++
PS : I downloaded the source code taking a look inside. I increased bullet velocity and I have modified some parts to get the game in fullscreen. Funny cheat :)
