This is a really cute game. It's a great concept and quite fun. If you went further with it, you could make subsequent levels more challenging by making the bombs colorful also. I'm not sure if there's a win condition, I got a score up to 53 but it just seemed to continue. I did check the lose condition, which worked well with the restart button. There were some minor touch/tap problems (sometimes the taps weren't recognized), but no other problems. Fun game!
