Awesome idea ! Game is some kind of puzzle crypt of the necrodancer, great concept. Also the groove mechanic is super well thought, the whole game's design is really great.
Took me some time to understand how much you could almost skip some levels with the groove, didnt expect the groove to not dropp when you dont move . My only feedback would be to maybe make the fire hurt only a little moment after it changes position. The fact that it insta-kills you once it switches pushed me to make the moves slightly before the beat, because being a bit late is much more punitive than a bit early and made feeling the groove IRL a bit harder.
Game is still really really cool, nice level design too.
Oh and the dancing duck is goated. One of the cutest animals of the whole jam
