This review was originally posted on VersionTracker.com. Really polished look and feel that helps create an engaging game. It has just the right amount of awesome 'squeekiness'. I think it's a little expensive and that is playing into whether I buy it or not.
For suggestions: sometimes the balls are switched to a position that makes a match, but then they 'switch back' as if it isn't a match. This makes you lose precious time and is annoying. Also, as the levels increase, it might be nice to have other 'weapons' besides the panic button (that you could select before the level starts?); maybe a click that blasts a certain number of balls out or a certain color, or lets you destroy a black ball. Finally, it would be nice to have the option to have the game pause in between levels (like a 'get ready' thing). This could be in the prefs. Overall nice job!
