Hate the game only played because of the card. The last level needs a checkpoint at the boss fight ~ went thru the entire level 3 times and haven't managed it. It also penalizes your cash when you die. May you die a dysentery.
This is an excellent game. All of the units are useful for something and the game is well designed and balanced. I think it would be even better if it had a map editor so you could make and play your own maps. 4/5 stars it would get a 5/5 if it had a map editor. I also added it to my favorites.
