Wow, that's really cool! I was listening to someone's Chiptune entry to the OST Composing Jam #7 and it reminded me of you, so I wanted to see whether you made an entry for it as well; instead, I found this beauty! Really cool. I already thought that it must have been partly 3D-animated (no way that anyone can draw that rotating square in the microwave so cleanly!), but that, 3D-animating, too is hard. Your 2D and 3D blend together real smoothly - I mean, I wasn't even really sure that you used 3D until I read about it. And, as always, congrats on just finishing something, that is hard enough by itself!
Oh, I just noticed this is over a year old... still impressive though :)
