I plan on writing more about this as I progress, but if you're looking for a bizarre perpetual running platformer crossed with a rhythm game, this is your jam. These games are frustrating, to be sure, but much like Super Meat Boy there's no better gaming feeling than acing a level.
I've been playing this one as well. I am so into it. Bit.Trip games rarely fail to please, but I really feel this is their best one yet.
