I'm stuck on level 5, that might be because I'm stupid. 🙂 It took me a couple of minutes to figure out that to rewind your steps you have to select the step you want, move down, and then press space; for me, it would have worked better if you just select the step and then press space without needing to move down to confirm. I like the art. It's simple but very cute, has a good palette, very cohesive. The music is also good, just really pleasant to listen to, I like all the pauses in it.
