That is what I imagine is THE game jam game. The game doesn't have a lot of depth, but it doesn't need it because you went all in on that breakdance gimmick and that's awesome, because it felt so polished and cool!
I'm not a rhytm games player, but this one is pretty forgiving and doesn't cause frustration. The visual style is also interesting, not entirely my type personally, but the moving pedestrians or cars through the screen and first part of the ending really won me. Also it's nice that the ending isn't only a cutscene so also props to that.
I don't really have anything bad to say about this game. A very polished and enjoyable experience, great job!
