This is a really nice genre mash up. I liked the concept a lot, but would urge you to make switching to turn based play easier.
The game is easy to understand, but by default it's really tough. I tried inputting the konami code, but died every time I did. This isn't surprising as pressing any key just immediately starts the fast paced game. And you die instantly. Just one mistake and it's game over.
The classic Snake game gave people more room to manoeuvre around. Some of the corridors become really tight and hitting a wall is an instakill. Bumping into baddies is an instakill. At one point I died crashing into a wall I couldn't even see as it was off to the top of the screen.
