I bit. Pretty much a typical iOS rhythm tap game with an adventure tactical layer and some minor RPG elements. So the way I'm rationalizing it is I just put $23 down for a solid soundtrack with an amusing game to play while listening to music. Price point is a few dollars off when looking at it like that, but the music is right up my alley so I'm good with it.
Fun for what it is, but sad I'm not Asian/SC2 player and can't play above easy difficulty - frequency of inputs scales ludicrously out of my ability.
