Not bad at all
Very original idea (you don't see to many of those anymore) and nicely scripted too. It was entertaining too. It was a little too simple for my liking, however. If you were to add some powerups or enemies or something (maybe there were and I didn't get far enough?) it would be a lot better. And maybe add some more colors.
Anyways, I'm being really critical, this is a great game with a great concept. Good job, keep it up!
