The art is excellent and the gameplay is decent, but:
It's a bullet-hell, but no clear hitbox (is not the same as the model) you can not understand how to properly avoid attacks, making already intentionally difficult gameplay seem not only annoying, but also unrewarding, as you don't know how to dodge
It has incredible multi-stage art, but why aren't we ever able to see more of the steps? Sometimes sexy clothing > no clothing, it's hard to appreciate it only during bullet-hell sequences.
