A Rather Good Game
I give you 10's for things like violence and humor because although there wasn't really much, there was an appropriate amount for the game.
The collision detection was a bit off, and momentum would be good, but other than that this is a really solid game.
One more question, though: if I turn off the monitor and speakers and don't control the cat, there's a chance he'll die and a chance he won't. Is the cat in an indefinite state of neither life nor death until the monitor is turned back on?
