The movement of the snake feels great and I love these kinds of games. I’d suggest a couple improvements.
- What’s the incentive for eating and growing? I was expecting some kind of score boost somewhere.
- Don’t start the snake movement automatically, wait for some keypress.
- When the snake’s head hits the wall, have it slide OR stop the “body” from “following” so it maintains its shape. Otherwise it’s quite easy to cheese the game by just curling in a corner.
