Got to dance score 108. There are two main problems, I think xD.
One is that it's very slow and that makes it far too easy, or too hard to lose depending on how you see it. In the end I lost because I got bored, instead of because of lack of SKILLZ. The other problem, and this is a bigger problem: There is no failing conditions for pressing buttons, I can just spam all cursor keys, which makes the lack of difficulty even more lacking (? though judging from the jam's theme, wonder if that's actually a FEATURE!).
But I like the idea, I love rhythm games too. ♥ WOWIEEEE!
