A hard game, but once you get used to it, it tends to work out. It reminds me of limbo on the level of differentness, and how hard it can be. Really the only annoying part of the mechanics is that you can get stuck on the line very easily. When you are stuck, it doesn't matter how many times you press space or even leave it go, there's no getting out of it, and you just wait and watch the red block finally come and push you off. I would add a bit more to the game as well, but for the most part, it's a good idea.
