Pretty fun game. I think the enemies get a little lost since they're similar colors to the floor, they were hard to see. A few times it seemed like they were killing me from offscreen before I even knew they were there. Love the overall feel of it though, great work!
Took a minute to figure out the controls, but once I got it it was nice and simple! I'd suggest adding a brief "howto" screen at the beginning. Very difficult game but also very addictive - will be back to play more!
