At first I didn't get it at all, but then it clicked pretty quickly for me ^^
I haven't seen anything like this before, and I think it's really funny and creative. I didn't play all the way to the end because I didn't know how many levels were left—I think I played about 10 levels. The difficulty was just right for me, too—not too easy, but not too hard. There's definitely a lot of potential here ^^
Good game ; )
