Too difficult for me, got close but couldn't quite get through it, even if I pretended Alice is Yachie. Enjoyed the game, really liked the writing. Collisions could use a lot of tightening up - maybe it's just the hitboxes being too small, but I feel like I got through a lot of squeezes that should have squoze me but didn't. Good amount of variation in the "pipes" as an obstacle while fighting Reimu - doing a lot with a little.
Do you attribute the music anywhere? The Eternal Shrine Maiden sounds an awful lot like the actual song.
