This was like ice skating and not knowing how to use your skates to stop. It was an interesting experience. I really liked the carving mechanic. The level editor was a cool idea.
The controls were complex and difficult to master. There appears to be no point in jumping without Shift being held down. It didn't help that the first tutorial level requires you to figure out the controls, and then the second one actually tells you how to use them. I did not try the level editor because I found the player too difficult to control.
This game has a lot of potential with some tweaking to the core play experience.
