The graphics are interesting, I like that there is a reflection. They reminded me of HYPER DEMON a bit.
The music is nice but what I loved the most was the shooting, it felt very satisfying both soundwise and mechanic wise. One thing I would personally like is if the enemies can't spawn that close to the player. I died a few times by enemies spawning basically inside me without having much time to react. But other than that I had fun and tried getting a better highscore each time
