This one is very fun to play! A creative use of the theme for sure. It was very satisfying to throw the ball around and navigate the level using it, I think you're onto a solid concept there. I also liked how the ball was heavy enough to pull you over a ledge so you could throw it and let gravity do the rest of the work.
When it got to the levels where you essentially had to cheat (throwing the ball and catching it mid air to throw again), the controls got a little annoying, I'd have liked the throw and catch to be the same button (especially as you can't pick up the ball unless you're next to it).
Other than a few bugs here and there (mainly with the collisions, and also that you can walk really far into the doorway before the level ends), this is a very well polished game and I enjoyed playing it alot.
