Wow, that ending xD.
This was an interesting experience, create your own danmaku patters seems quite nice, but once you got the hang of it, you can actually cheat a little, other times you create impossible to dodge danmaku, Sakuya has a ton of life, so nothing to worry. Some obstacles on the floor could be added to increase the difficulty, but it's nice how it is.
Actually sakuya's sprite is sorta misplaced, when you approach the couch, she looks like she's under it xD.
Flan wings music game was the best, it remided me of the gud ol times I played Donkey Kong Country 3.
