Trick 1: In the part where you have to dodge the balls in dizzy heights, if a ball is coming you're way, move to the nearest wall and walk against it. (To know you're walking against it, it should show a pushing animation on the brick.) And for some reason, the ball doesn't hit you.

Trick 2: When you face the swinging balls in hit parade, move to the right or left. It let's you avoid 4 to 5 balls and most of the time you just walk through with a breeze. But be careful. Near the last to swinging balls you can get hit which will be a devistation if lots of people are already qualified.

Note: i made a post like this on Steam that is similar to this one, on my profile you can find my steam account there and you should be able to find the post, i'm new to steam, i don't know alot about it :T Just wanted to inform for those who thought I stole this trick
