What an amazing concept! I love your very creative take on the theme, finally a bit of originality in the jam =D!
The game design is awesome. I don't really understand how you read the theme and immediately thought "yep, that's about a snake-like puzzle game, obviously", but I'm really glad you did ^^. It's a very interesting take on a classic game, and the puzzle mechanics are clever and intuitive. The sound design is simple, but perfectly fitting. The difficulty curve is really good, and the level of polish is just amazing for a one week jam.
I'm impressed. Congratulations to you, and thank you for those enjoyable minutes I spent on your games. You are the first time, in this jam, where I'm a truly disappointed when the ending screen appears. I want to continue playing, but that would be unfair to ask for more in a 7-day jam =p.
