It got the 4th star because it is an addictive game once you get your feet off the ground. The problem I have, as like some of the other comments I have seen, is that the gem prices are ridiculous...Lower the cost of gem usage on the game for the individual uses i.e: building upgrades, units, ect. You'd make more money...I know I have thought to myself "if these b*tches were cheaper I may buy some.....but nope.

Fun fun!

Yea this game stinks!

I would have given 5 stars but the controls on my iPhone could be a little smaller. Seems to kinda get in the way. As for my iPad, this app is 5 stars. I remember playing this at the arcade with a joystick and 4 buttons.

This was terrible. I wish I'd have read these reviews b4 buying this. Oh well there goes ten bucks. Beware app is crap and does not work as designed.
