This is adorable! The graphics are great, the music is great too. The gameplay is kind of simple, but that's all right. The only things that bothered me were, first of all, that you have only one "life" and then things are over; it seems kind of arbitrary and unforgiving. And second, what I'd really like is to hear some audio cues when you hit the right keys, like the music changing for a moment. Other than that, though, great job!
