left a comment on the game page too. more seriously, this is actually kind of a unique mechanic, having to recognize whether colliding with something will extend your combo or count towards ending your streak not by anything as obvious as size, shape, or color, but by something trickier to judge from far away, like animation. (I could generally recognize people doing chicken dance or YMCA, and anything that wasn't one of those I tried to steer away since I was never confident someone was doing hip-hop mode)
