Pretty fun. The techno music goes well with the flashy colour pixel art. I'm in love with the chunky pixels. Gameplaywise, it is fast paced, really gets you thinking. I like how you can adjust the speed of the snake; it makes for a crazy challenge up in the higher difficulties. The gimmick is interesting too - shrinking rapidly instead of hitting a wall decreases your "nom" score, but still gives you an opportunity to react, along with the slow motion. All around good stuff!
If there's anything to complain about, I didn't particularly enjoy playing this on a gamepad. Using only joystick controls, I dunno, makes it harder to play in a less intuitive way. I'd prefer the D-pad buttons, but maybe others don't play it like that? Could just be me.
Lastly, the halt noise and humour in this game are well placed. And amusing. This was very enjoyable and cute. The bosses had me surprised, too.
