Very cool idea. The rock falling is unfair and sometimes huge rocks block the way so there is no way to dodge them. Probably instead of time freezing you used time rewinding, it could be a fitting fix for this issue. Otherwise the constant 90 degree turns made it really hard (at least for me). A cool concept for the corners would be some camera trick, where the camera yaws towards the turn's direction which would let you see more, feel the pressure of the turn and it would fit the vibe of the music.
Speaking of the music, I think it was very fitting, loved it.
