I enjoy the concept a ton, and though I understand the light moving around to the beat of the song, if there was maybe a way to change game modes to something where the light moved faster or the player didn't have that constraint it would be a lot more friendly to people who can't really see a ton of steps ahead like me :,)
A game mode where all the mirrors and lights moved every time you moved could circumvent that problem by making the light spin at your pace, or something along those veins.
All in all great stuff!
