Aesthetically, this is incredibly compelling. It's also very, very hard, I could only survive a minute or two, but I reran that little bit over and over to see the visuals and hear the music. That said, as another commenter mentioned, the sound effects need an update--mostly just to reduce the volume of enemy death sounds, which are grating and very frequent. I was surprised I could tune them out after a few minutes because I enjoyed the BGM so much. You're definitely cooking with this.
