Very nice art and a really cute main character for the main PC, I had a fun time playing. I like the concept, but it was kind of a guessing game at first as to which blocks were which for each level without using the help button on the side. It'd be nice to have a way of knowing what the blocks you're pushing around sound like before arranging them, such as when the PC touches them.
Music arrangements were nice and worked well, but (as a personal take only) using copyrighted material, even just arrangements of them, is something I would avoid, but whatever works for you. That being said, thanks for the experience!
