This is really sweet! I had to read the comments before I understood that you didn't need to stand on the things but you just needed to hit the direction the dot is on. I think a big reason why this trips people up is because the first one is timed such that you can perfectly step on the footprints to the beat so it teaches you the wrong thing. Once I understood the idea it was super fun! I wish there were more rooms, I was just getting into it ^^
I think the art is actually incredible. It has a really great style. I think the next room animation is super slick. I think this one is a little gem and I think you could do a lot more of this.
Well done!
