Controls were very imprecise for me. Felt like running on ice, which made it difficult to get anywhere. Also didn't know where to go in the end. Tried to jump onto the spaceship, but couldn't. It just kept pushing me away.
The rotating things rotated so far that you could no longer see the rotation. But I was able to stop it with a block.
The idea is nice, though. The combination of a parkour with the addition of being able to build stuff if cool.
