Not the first inverted snake of that I see in th e jam, but this one has a beat! Really good presentation, the music is good, the snakes match the beat, at first I tough this was a rythm game..., and the graphics are neat, I especially like the apple being eaten when you get hit, such a nice touch.
The only little details I can think off are I wsh there were more levels (but they feel handcrafted and not random) and the game screen felt a bit empty, maybe adding a track playbar at the top or bottom would be nice.
Overall, very solid entry! :-D
