Cool effect with the ground and I like the aesthetic of the game! I am a sucker for neon.
Sometimes I would shoot at an orb a few times and the bullet clearly goes through it but does not collide until I reposition to another side.
And the timing of the beat doesn't seem entirely accurate. It seems to shoot a bit before the dot reaches the circle on the visual indicator. I cant comment on audio accuracy as I am using bluetooth headphones and there is no way to adjust the sound offset which is common in rhythm games.
The only audio appears to be the same constant beat. It would have been nice to at least have a gun sound effect.
It is an interesting and good concept that just needs some polishing and extra content and music.
