Rhythm game. You press A when you drive over a square, when the track turns you press left or right into it, when spikes on the ground or rings in there you jump over/through them. Everything is scored with timing a la Guitar Hero with good/excellent/great. Miss a turn or hit spikes you lose health/multiplier, two hits you are dead (can regen health by successful combos). Miss a beat (square) your multiplier resets. Top level play has tweaks on the gameplay, more points for being in the air on turns, ground pounding notes, etc. Boss fights include properly chaining all this together and attacking them by hitting an attack beat.
The music isn't really music (well of course it is) in the traditional sense, but (industrial is a good word?) beats and a feel you get after playing. The turns come so fast and the music gets so ingrained you start anticipating things before you can even see them. It's really bizarre and in VR I'd have this weird fuzzy feeling for hours afterwards (I didn't have in other games) and I'd be tapping the beats long after.
