Playing through again, I ran into one problem.
On level 14, it's possible to get stuck between one of the rings and the wall.
While there are all sorts of Rock-and-a-hard-place jokes to be made there, I'd prefer to get back to fattening the kitty.
Fun game, all the way to the end.
I loved the little comments after each level, and the music was pretty good.
Though it is slightly depressing that I now hate hedgehogs.
A lot.
