For level 20, use your wench near the top of the tower, pull it twords you and fly through. If you've done this correctly, your tower should still be standing.
Well, it will probably have some glitches when it comes out, but they will be fixed. Really looking forward to the launch, even though we'll have to leave our profiles behind.
You have to drop weights on the bars to keep them in the middle. I remember playing this when there wasn't music on there. Then, I thought it sucked. But I like it now. :D
