Good game.
I have no idea what the hell you guys are talking about. This game wasn't hard after you got the hang of it. It took me maybe 30 mins to beat it all the way through. The graphics were good, with maybe a little work needed on the rock cliffs. I definately missed the sounds of the turrets firing, though. Also, more units would help, like an airport that bombs vetically across the screen where it is placed, taking a little while to recharge. This could be used for last ditch efforts. Also, it would be cool if there was a building (perhaps even the factory) that let you increase the max number of turrents avalible to build. Also, bigger maps and more paths for the enemy would add more stategy. If unlockables (floating turrets, mines, long-range turrets, maybe the airport) were rewarded for perfect level completion, the replay value would be much greater. Good game for pick up and play, but it needs more depth to be anything more that that.
