Interesting idea for a puzzle game.
The thing I wasn't very happy about was why loads of numbers decide to change from being 3 just as you are about to click on them, getting a penalty against you. If you could explain more how the logic of the game works rather than "just click 3" I'd be happier with the game.
Nice music and decent graphics and UI are present in this game.
I'd have rated this higher if I understood it better.
