Very short game which didn't play all that well. Most bosses have a couple of attacks they cycle through, which are very easy to learn.
Timestop and spell-variety are cool mechanics at first but very quickly mellow out to be somewhat boring. Half of this game is spent parkouring awkwardly and finding out where to go.
Best part of this game is the music and its cute visuals.
It's a hard sell - would only recommend it to people who really just want to play a touhou game with touhou music.
