Solid overall with some cool concepts! Sound is a bit lacking, but the pixelart is nice and the controls work fine, I especially like the Satori (and theme) fitting mechanic of learning new danmaku from defeated enemies. The boss fight was really cool too, I liked the dialogue and it felt pretty fun to zip around switching between attacks while dodging the falling ice. If I had any gameplay critique, it's that Satori feels a little too fast, so the dodge in comparison doesn't feel very special (minus the iframes!)
