Nice entry :)!
My feedbacks in two words :
- The level design is cool, but there is a little lack of variety. I mean, without minimap it's pretty hard to realize where you are.
- There is no reward to eliminate the enemies, and since it's pretty long to kill (two charging shots for the crawling one), I prefere dodge because I know there is know reward.
- The artistic direction is nice, and story too!
Good job!
