Poor fish... What did they ever do to you, Okuu?? 😭
It's been some years since I played a touhou, and honestly - this wasn't a bad way to get back to it. I enjoyed it, even if it took me a while to remember that item autocollection and grazing exist... Even then, my best score is barely half of the top #1 lol
The difficulty is consistently high overall, there were a few patterns that were noticeably harder than the rest, but overall the balance seems fine. The only part that felt unreasonable was during Wakasagihime's Aquatic Impact spell, the tiny spaced-out bullets that appear from behind are really hard to notice, for multiple playthroughs I kept dying from them and wondering what hit me.
In addition, the fact that almost all bullets are pink made it way harder to parse attacks. If they had more detail or animation (like in Mushihimesama) it'd work better, but I understand this wouldn't really be touhou-styled anymore. I would just try and mix bullet colors a lot more.
The music is nice. Visuals are funny. Pretty cool overall. Congrats on finishing the jam!
