Gotta comment on the ' it's stolen' reviews. You guys think it's stolen cuz "it's too good"? LoL :D. The marble that looks so cool is a straight copy/paste from a tutorial I know. The upgrades just change a variable (wow advanced! *sarcasm*). And then there is hitTesting with square objects. Wow it's way too good (sarcasm again)!
It's a simple game with tutorial code in it. What bothered me was the super light UI. Did you put a white mask on top of everything? I really didn't want to concentrate to try to read your menu when it was so white. The game has plenty of newbie mistakes so I have no trouble believing it's your first game. Good job thought cuz it is slightly better than what most people do as their first.
