I really liked the music staff as bullet trail, and the room was pleasantly presented... Pistol Whip and Audica are the models for musical shooters, so some of those aspects could have been incorporated to either make this more melodic, rhythmic, or both. For a game so heavily steeped in musical props, decor and interactables, I'm surprised that the musical notes, when shot, did not play a tone, and so, there was no musical instrument to be had here. Any tune would have sufficed, so the player had a sense of contribution to the moment beyond target practice.
It's a fun little shooter, though! Gorgeous lighting and style!
