I dont understand. Is this an advertisement for another game? The link takes you to a game that costs 99 cents but the coupons go up to $9.99? Also the double face book link does not work.
This is an old advertisement, the game used to cost more when it was released.
We might publish the game here for free soon, so you don't actually need coupons anymore.
Please check our updates.
Very basic simple game. Good graphics but has a few irritating bugs. I enjoyed it for a few minutes before turning to something new.
It's alright. I don't really like defense games so much though...
