I also noticed what I think this post[1] is talking about, namely that
snake2 is a bit big for the clip zip's screen. The poster just calls it
"snake" though. I've sent a patch for review on gerrit[2] that fixes the
problem. It simply adds another ifdef block, with suitable values for
the zip's screen.

cheers
