Oh that's funny $hit; ha!
21: Dave once you get to the flame throwers, its easy with some patience.
To get there, you have to spin a 180 about halfway through so you can keep the ball on the plane opposite that 'horn' shape. Wasn't too hard. Wait till you try and get the ball to balance on the spinning stick in 22; I'm there now, I've got it through the first stick sequence and working on the second now.
The level, I think 20 with the orange tramps was frickin crazy; first you have to learn how to get past the 3 orange tramps and then those stupid horn shapes kept throwing me into the teeth; ha! Kinda cool the emotions it brings out...... I can only imagine one of those screaming faces at the right time and bang.... you're dead. Ha!
