Very nice game. It's sometimes a little hard to gauge to which sides the cube will "stick", for example in level 6 I can't roll to the end before the first yellow cube even though it looks to me it should work.
In the game description you said:
Procedural soudtrack will never be the same twice. It just remixes itself forever.
That sounds really interesting, could you explain how that is done and what tools you used to create that?
