Played the WebGL version.
I really like the idea and how it fits into the theme. It's like a reverse snake. I got stuck on the third level. The high speed of the worm and the frequency of the fruit was a bit too much.
It requires me to play perfectly to get all the salt and no food, which I feel is a bit unfair. Also, I don't know if it was intentional or not but you are able to turn around into your body when you only have 1 tail piece left. I don't feel that the music is the right fit and it's a bit loud and can't be turned down.
I did enjoy playing it, and for being made in 72 hours it's really good.
