LOVE the premise for this one. "oh no I can't danmaku time to use hot lead instead" feels like a very Sumireko thing to do.
The bullets not being hitscan took a bit to get used to, but thanks to the infinite ammo and the generously slow speed of the targets it felt pretty good to clear enemies out. Especially liked how their bullet patterns disappeared when they died, it helped encourage me to rush in and try and take out a few before the bullet clutter overwhelmed me.
