It's awsome! I only experienced two errors:
-If the ball hits the bouncy thing just right, it gets stuck inbetween the needle thing and the flat part.
-Sometimes, the ball hits the wall dead on, and if nothing's in the ball's path as it bounces towards the other wall, it will just keep bouncing between the two walls and won't come down.
I tryed to recreat this events and take a screenshot, but I couldn't get it to happen again, which is good, I think.

Anyways, that's all I could find wrong with it, AWSOME game! Hope to see an update soon!
