What a great game! I really like the atmosphere and lightning effects. I also appreciate the options and how you implemented options for key bindings. Gameplay-wise I like stealth games a lot, but I thought it's a bit too hard to sneak around in this one, especially as the energy runs out very quickly and I felt I had to take out enemies to get energy (it's in general hard to make a stealth game with time contraints). But again, great submission!
