Hi! Great effort. I like the theme that you went with. I found it a bit hard to tell where the obstacles were, and I kept eating soldiers, then getting hit by their torch beams even though they were dead :P Good job.

The idea is interesting, I love the idea of using darkness as a weapon, stealth is a fun thing and it allows you to feel like a true monster. I like how you implemented things very much, though I found it hard to move, with obstacles being almost indistinguishable.
