Really cool concept and application of the theme. The metronome really helps put everything together. Simple art style and witty humor between levels is also quite nice. I think it's a bit on the harder side as its quite strange to get used to, and having no way to learn the level except for running into obstacles makes it a little frustrating. I think a "free camera" or such mode may be able to help, where you would be able to see the whole level just so you can have a little bit more of an idea going into each one, rather than just waiting to die to see anything.
