Like the old times playing in a Nokia phone. The game is solid. The only issue I see it's the art. I also struggle to get assets which are visually coherent among them. In your game the 3 elements: walls, snake and squirrel have different visual style and definition. Having an armonic art style is very challenging in a short game jam unless you invest time in doing all the art by yourself.
Anyway, congrats for the game. I really enjoyed it.
