Nice game! Very interesting limitation use. The music and the art were good too and created an ominous ambience. The only thing that I found weird is that the fps dropped to 0 when you encounter a drone for a moment, and after some time it goes back tom normal. 

very strong game here! The level design was pretty good and the mechanics were solid. Only problem is that the game can get very laggy when you respawn.

Great use of the limitation and really cool but simple art style. Game is really impressive.
