Fun take on snake! I like how you get more points for the area enclosed which gives an interesting balance of risk and reward (and the scoring animation is very satisfying). The third level is quite hard, I usually use a zero loop to skip it. The fourth level is my favourite even though it's empty, it gives you a chance to freestyle without worrying about other obstacles aside from yourself. I was curious what happens if you made a loop from a straight line by wrapping around the edges of the screen and got zero points, which makes sense. Then I made a loop around the corners of the screen and got this result:
The art is cute and clean, and I enjoyed playing. Excellent work!
