At first I thought that this was a second version of a level so ignored it. But it looks like a completely new level.. I liked watching the ball being pushed along but that had nothing to do with the gameplay.
@Dave after you've finished your level, export it and then load it back in as if you were somebody else. Then play it through. If you can't beat your own level, when you know how to win, then nobody else (without using cheats or special moves) can do it. Just a little bit more testing will avoid problems like this. Thanks for sharing anyway.
