I feel like this game would benefit from having randomly generated levels, or at least a few patterns that would change each time you play. Since the level is really shot, it's easy to memorize it. Also the player collider still feels a bit too large. It would be great if the snake would be visible in the background and not only on the side of the screen, as looking there is quite distracting. (hope i didn't sound too harsh, just leaving some ideas for improvement :) )

I found the gradient a bit confusing at first, as it's hard to tell when you're in the gradient and how long you can stay there. Once I realised how I was dying, it was a fun game, great work!!! It's challenging and it fits the theme well. I'd like to see this with some random levels so I could play for longer

It seems to me most people don't understand how to play. You DO need to accelerate so the snake doesn't catch you. This may need clarification because it is not obvious. Regarding the gameplay, it seems a little rough and simplistic but enough for a game jam nonetheless.

Wish you made the players collider slightly smaller. Very hard to play.
