Hi,
I still don't understand the game, but I can only move the "snake" within a very small rectangle (or square) approximately at the center of the screen. It disappears on one side and appears on the other one, but of a small square, and it looks like it is supposed to do the same on the whole window, or is that the expected behaviour? It seems impossible to avoid the red circle while being constrained within a small rectangle, but maybe I'm missing something...
Apart from that, I get the error "click~: couldn't create": is that an object of PD Extended, or an abstraction that is missing?
Thank you for sharing the patch. I love games :)
