This was a ton of fun. I didn't even realize the levels were just looping over themselves until I played through like 8 times.
I loved the added mechanic of colliding with your own body. It was awesome building my own "snake-bridge" between paintings. I also really loved the gradient on the snake.
I could totally have accidently had the game muted, but I didn't really hear any audio. Some music and sound effects would really give this gift of a game that final little bow it needs.
Real amazing work and I'm excited to see what else you make!
