observations:
* too easy for too long, by the time I started to need to pay attention I was already out of it
* the blocks _almost_ fell in time with the music, which was a little disconcerting. sort of an explicit sync would have helped
* it seems like an ideal strategy would be to just circle the arrow keys really fast. Adding mechanics that didn't make that true, like a "blocked just in time" combo, would have made it more compelling to play
