I really liked the idea and some of the dialogue was hilarious (especially Hisami). Bonus points for being the first game I've seen this jam to have ZanHisa. The visuals were really cool too, I liked the cardboard cutout aesthetic used for the danmaku. The music was good but could have done with maybe another song or too as it got a bit repetitive. The gameplay was fun but too easy; many of the patterns were too simple and static and I instantly figured them out. Others were very sparse and had slow-moving bullets. Overall the difficulty felt somewhere around a Touhou Easy. If there's ever an update, I'd love to see higher difficulties. I went for all the spellcards and captured them on my first try, but it could have been fun to try to guess all the items instead, since many of them could be figured out from the context.
I also encountered a few glitches. When pausing during the danmaku segments, it doesn't actually pause the gameplay. Sometimes when finishing a spellcard, the bullets would keep spawning for around a second and then go over the UI.
