Finally getting back to playing and rating games... sorry everyone!
There's a lot I like about this one! The art is excellent throughout, the audio all works well, and the silly story is fun. I like the concept of the magical girl being a machine gun toting Oni.
The gameplay works, but could use a little more tweaking. I think someone else mentioned it already, but the transformation, while cool, was under-powered feeling, and actually made fights against the thugs very hard, as the barrel of the weapon would stick out past them if they were close by. It did come in hand on the end boss though, for bypassing her shields. Not sure if that was intentional. I also found by spamming the attack I could defeat enemies way before they appeared on screen. for better or worse.
Despite some rough areas in the gameplay, I did enjoy this! Nice work!
