rather buggy. I think I have 3 air towers on top of each other in the middle of the screen. Upgrade button stopped working until I build something I didn't want.
The biggest pain in the butt about this game is that the units stop behind each other, even when they should be attacking (the red circle appears)... I assume that the plane continuing to fly -to- the target after their payload is deposited is also a pain. Why do the units each need to be their own team? That's why.
It should save, as should any game that takes so long to play, despite the obvious problems associated with retrying levels and getting the highest scores my min/maxing. It's a game-play enjoyment problem, and that trumps all, even the competitive aspect.
This game is fine until you get to lvl 21 on insane. Suddenly, the only way to win is to play until you get lucky pickups from the stupid airplane, and whats more, you apparently have to win this level to get to survival mode. 4/5 just for the stupid, probably last, fight.
I understand the kong is interested in trumpeting its core supporters with badges, but it needs to support these blockbuster games with badges or lose the spirit of the site. A badge 'splurge' may be in order. Along with the necessary small amount of 'point/badge inflation' natural to such an "economy."
