Found myself mostly looking at the Windowbar to find what key to Press. I think it needs a lot of time to getting used to actually memorizing the Dances.
Was super lost in the beginning, but then remembered to read your Games page, easy mode makes it really clear what the Game actually is about, good Job.
The Animations are nice.
I think for hard mode that doesn't have the Dances visible during input, some kind of idle dance to play while its waiting for your input could be nice, so you can have a constantly dancing character.
On that same Note, it would really be great to have the interface on screen and not in the windowbar, and have some music to go with it, but obviously that'd be if you intend to continue outside the filesize.
Nice Game overall, good Job on keeping it below 64kb.
