Glad you had fun with it. Kaguya is quite the troll, she's caught a few people out who aren't aware of her legend. And the game is capable of being beaten in any order, so no one stage is more powerful than another this time
In the future, I may get Melin to make me some more tracks, but I personally think the length is good. The character themes I have for Housekinomon (not the Chibi Jam version) are the same length, and they'd play for longer. If I did get Melin to make me another track, it'd be for the battle, or for a new area I have planned
