Can't get past the first one with the rubber things.
Not too tough. Just use a 10 or 20 ball, click the top-left of the circle and drag to the right, aiming towards the left/top-most part of the bottom bumper. That should make the ball bounce up and into the side of the green blocks.
A little after posting I'd completed all the levels and all the challenges except for one. For some reason, I can't seem to complete the challenge on level 27. If anyone figures that out I'd love to know how you did it.

ps- happy birthday!

Ahh, figured it out. All levels and challenges done now. I really enjoyed this one, and wish there were more levels. Here's how I did the 27 challenge:
using a 5 ball, start at the very bottom of the circle, drag far left, and aim towards the top of the exploding block. the ball will bounce back and knock down the long block.
haha! and it is pretty worth it to beat all the challenges, because the evil vortex ball is pretty fun. Not very useful, but fun
*last edit, I swear*
I stand corrected, you can beat at least 2/3 of the levels with the vortex ball alone. Sweetness. I highly recommend getting the vortex ball and playing level 15. Fun stuff.
