I like the psychedelic kind of feel for this game. The music and the character sprite are great, it invokes feelings of a... DJ? Anywho, you don't often see this kind of mechanic with a 3D platformer, which is a good thing - it's original!
As a 3D platformer, movement is a bit loose and leads to death sometimes. It can be a bit hard to discern what exactly needs to be done sometimes, partially due to the world floating out in space. I think a couple blocks as different colours would make that a little easier.
One other thing is that the "power plug" sprite was a bit hard to figure out, it initally looked like some kind of robot face.
It is a little unfortunate that there aren't that many levels. I would have liked to have seen the mechanics played around with more. There's a lot you can do with timelines in 3D space!
