that took bout 10 minutes, good idea for a game but it was too short and you dont even need half the upgrades just the fuel, power, roller-skates, and the slingshot.
a few weeks ago, i loved this game! Now whenever i die on the ten hydra (you have to die and revive to beat it most of the time) it goes white. WHAT THE HECK MAN!?!?!?!?!?
I am not a big fan of the other bloons series games but this one is GREAT! The graphics areamazing, there are multiple awesome upgrades for 17 towers, and there are daily challenges and special missions that rock!
there should be a bonus level that costs 10 gems ( how much you have left over if you get all achievements) otherwise i give it a 6/5, yeah i went there :D
