Thanks. I tried making the tail remake your steps but that made dodging thorns easier, which defeated the purpose of choosing between swallowing the food right away or keeping it for longer. Making the tail follow you made it very complicated to make the head collide with the tail so I did some testing and decided to allow the head to touch the tail.
Music was made by a friend of mine, he's very talented. He made this one for a game that never got released and he thought it fitted my game so he allowed me to use it. I think this song is pretty simplistic compared to his best work (and he does too), probably because it was intended for a simple math teaching game.
