Very cool, the highest score I was able to get is 1200!
I’ve seen this idea a few times so far this jam, but it is a very good execution on it. I love that the game starts with the snake eating its tail, showing the player how it works. Though the counter should probably start at zero, so that after the demonstration, the level counter is at 1.
The screen effect was also really cool, but a little strong. It’s very stylistic but it obscures the game a little too much in my opinion. Perhaps a lighter version of the same effect would work better.
In any case, well done on this submission!
