if youre looking to get into bullet hell games, i definitely recommend this one because its beginner friendly. it also has a funny dialogue as well as a funny story. huge recommend for touhou and bullet hell fans

It's got Apple Girlington in it.

legal!!!

Super fun and tight fangame that doesn't take itself too seriously and is legitimately funny at times. ALSO FREE, great experience.

The whole game and its bosses are mostly about pop culture and foreign concepts intruding in Gensokyo.
