Neat game. I like the idea of a Snake type of game where you can eat your own body; it makes me think of the Ouroboros. Plus the music is funny.
After losing a few times, I struggled to figure out what I could do differently in order to play better. I'm not sure if I was completely understanding the game or not, but it felt really hard to survive after a short while.
Couple small things:
-Try to present information in-game instead of using pop-ups
-Consider allowing W/A/S/D to move in addition to arrow keys. Different people prefer one or the other, and having options never hurts
Grats on your entry. :)
