Thanks for playing!
I'm glad the music was helpful. The main reason I spent so much time on it (unfortunately at the expense of the sprites) was because I wanted it to really fit with the game - that's why you'll notice that in addition to the panning, certain instruments (e.g. kick drum) usually only play on your turn while others (e.g. snare drum) only play on the obstacles' turn.
That said, while part of the reason I decided to go with a minimalistic art style was to save time, the other reason why was because one of my inspirations was Laserwave (which also had a similar minimalistic style with polygons, albeit more neon).
