I really like the premise! I believe this is an idea that with some more work would turn out just great.
A couple things would probably make it more interesting to play though:
- 10 secounds feels to long. If the levels were built around a shorter time frame, like 3 secs for instance, maybe the platforming would be a bit more engaging and fun. As it is, it gets frustrating sometimes.
- No problem with the music and its catchyness, but I wish it was more apparent when it was getting to the end of each segment so it would be easier to understand when the change is about to happen.
Also, as ZamuraiX mentioned, a restart button would do wonders!
