I'm at about level 64 and the game has become near impossible to progress.... Despite spending ~$5 to get extra Bloon tank, near impossible to get more Bloons and progress past my level. Out of powerups and not getting any anytime soon. This is despite viewing inane Ads at every opportunity when given for little extra boost of pink stuff that makes crystal Bloons. It appears that, despite their socialist government, Kiwis are just money-grubbing capitalists in the App market...
