OK, after playing quite a bit more of it (I've nearly finished to level 3, not including the tutorial one. You know, the one with the dark matter), I have a couple more things to say.
The system you've made makes for so many unique scenarios, which is really cool, and you've been very creative with the level design, I love that :)
You do have a problem with the music synchronisation, though. Sometimes it's in time, and it's magnificent, but most of the time it drifts out a bit, and it loses that magic, although it doesn't ruin the game for me, I can still get the timing right by looking at the red circle at the bottom, and enjoy the it very much still. That would be the first thing I'd try to fix though, as it'll make the game much more satisfying :)
I had a similar problem with my game, and to fix it, I based all the timing directly on the music, in the code, rather than maing them separately and then trying to make them match. Does the software you're using have any way to get how far through the song you are, because that could help?
Also, when you tell the player about the dark matter, it's not very clear that it's coming up from the bottom, acting like a time limit, so the wording there could do with tweaking. I didn't realise that and just thought it was a bug, on the level after the tutorial, because I didn't notice the text at the start of the level :P So that was annoying :D
Also, I've had a couple of times where I jump while I'm on a platform moving upwards, and I go really high in the air. Just thought I'd let you know about that bug (I assume it's a bug?), if you didn't already know :)
Please understand though that these are just minor things, and all I'm trying to do is help polish an already brilliant game :D
I've been playing it for a few hours now, and I'm still enjoying it :)
Oh, one last thing: how many levels are there? :D I'm just sort of blindly continuing with the game, but I do need to go to bed at some point :P
