Note: It took some time for me to get back around to finishing comments on the jam games. Pardon the late comment!
This is a well executed bullet hell that does the formula justice! It looks nice, between the UI and the colorful character style. The gameplay, of course, has a lot of fun foes and patterns as well.
I did notice the music being a small issue mainly on account of the empty air at points - especially the title screen and ending cutscene. Otherwise, it's a good one song that doesn't overstay its welcome too much - and a fun Touhou-style one to listen to, on that note.
Overall, however, it feels very alive thanks to its own fun and ultimately quite wholesome story, so I enjoyed it. Well done on putting this together!
