So, i like the concept, but game requires a little bit of balancing. The enemies can come from the shadows right behind and kill you. Furthermore, they can spawn behind you! I just cleared a room and was shooting at some doritos when from behind spawned one and killed me! Also collisions are a bit off, there are spaces where i should be able to fit but i don't and the doritos can kill me without even touching me :(
Regardless, cool idea!
