This game is pretty cool! I actually like it, and I like the music. There's only that one scene though (is it just one I only was able to play one).
If you could do more scenes it could be great! I actually think the art looks good too, I think it fits pretty well even though it's simple.
If you could make a system where you could chain together your own combinations of lyrics, it could make the game interesting. Kind of like points to pick or something, maybe more ability to control your own lyrics.
