This game is insanely fun and addictive, I've cranked more hours into it than mainline games. While I don't enjoy the fanon tropes of Touhou too much, the story was pretty neat and trying to figure out the preferences of everyone was a good time. The soundtrack was lovely, I have songs that will stay ingrained in my head for a long time.
Definitely give this a shot, it's worth all the money it asks for
