ok if you can speed up upgrades for free that are under 5 mins then why cant all upgrades in the game be lowered by 5 mins (may not save much time but every little helps....).
hmmmm do you know what im thinking oh yeah UPDATE THIS GAME OTHERWISE YOUR GONNA HAVE PEOPLE GOING ON FACEBOOK PLAYING THIS GAME FOR THE NEWER STUFF E.G CHAMPION CHAMBER AND FORTIFICATION!!!!.......sorry i got a bit carried away
rate up if you think there should be minigames to play while you wait for your buildings to be upgraded/builded such as (you can use a turred to kill the pokeys coming at you) or (you can control a rocket dave that destroys up to 50 bases)! these are a few shit ideas for minigames so as i said before rate up if you want the developers to consider this idea!!
