I've got an idea for the 3x3 theme, but it would require some music - something 8-bit/chiptune, loopable, and with a very peppy anime-ish feel. Think 8 bit Hare Hare Yukai! Also I'd need a couple sounds - a very cheerful chime/bell (think like when you pick up a bonus coin or star) and a more subdued sound of a similar type for regular use when shuffling around stuff (the idea is for a puzzle). If you think you could do it in three hours please answer here and we'll see how to get in touch!
