This game is similar to Castle Raid on the app store. Use the mouse. Sorry, but I'm not updating anymore.
One cool thing I thought people would like to know is that the bullet is the same sprite as the thing shooting it. Got the idea from Castle Raid on the app store. December 22, 2014 New enemy bomber planes, making trenches more vulnerable. You can now win the game with missiles(but the enemy has them, too). December 21, 2014 Enemies spawn close together in waves(which makes trenches more useful). Player troops can die and get injured. Enemy trenches, making planes useful now. Sounds for troops. December 20, 2014 Game release.
