I'm a little late on playing this one. Playing it though, I don't understand why there are no badges for this game. It's fun, semi-challenging and offers some replay value as well. Mid-game could've used some more action and maybe a bigger variation in enemies might be appreciated, but overall, a very good flash game.
How about a button for deflation-mode, where you can "skip" levels, being a button you can press that instantly calculates how much bloons would pass with you current settup and makes that happen instantly. Would love this as an option, because when you're stuck at a deflation level, having to play it all over again (with the first 20 levels being easy as hell) would make it more gamer-friendly.
