I needed a walkthrough to complete the last level -I couldn't figure out how to finish that last one-
Undoubtedly, the hardest of the hard badges. Wonderful game, by the way ;)
Nice game, reminds me the classic Volfied in some way; though it's pretty easy to fill the upper corners with a bunch of medium sized balls until you reach the goal.
Loads of people have said that - I never played that honestly!
