Playtest (no commentary):
This was fun! I tried the game at an older demo day, but that was a couple years ago.
The cutscenes are cute and the first level is fun. It's a nice way to introduce all the characters. The game itself is also pretty unique; feels like an MMO combined with bullet hell. I'm not into the grindy, loot-based gameplay of those types of RPGs, but plenty of people enjoy that, and I think it's a sensible combination. The bullet hell aspect prevents it from feeling mindless.
There definitely should be more feedback for when you get hit (sound and vfx). Maybe a timescale slowdown too, so you can react to it. The difficulty is fine, but I found that I took damage without noticing it sometimes. There might be balance issues with the characters as well - the fire girl seemed like the easiest to use, and the crossbow girl's RMB attack felt risky because the charged version just makes her leap into harm's way.
I'd also suggest changing the main dialogue font. Right now it looks generic, like Arial or Helvetica or something. Funny enough, it actually looks soulful in the sense that it looks like a Japanese game where the localizers didn't spend much time figuring out a good font for English. But yeah, any lesser-known sans serif font should be fine... maybe even Lato (the one used here on itch).
Overall pretty solid gameplay, and the Touhou vibes are strong.
