It looks like I'm in the same boat as a few other people. The exit button doesn't work on some screens, and I even had to exit the tutorial to pick up the first package. No buttons worked except for the options menu and the exit tutorial button.
If the purchase of this game included a copy for Android phones/tablets, I'd definitely be on board to buy it, but as it is, I can't see myself buying a flash game based on Kongregate. Sorry.
