Cool game! The Dragon looks really funny, as do the Hobbits. Can I make a suggestion? The fire balls should move! You could also add a score, and levels. But great game! I said I wouldn't be disappointed!

There are some problems: the tanks can get stuck when they switch sides of the world. Also the enemy tanks have unlimited ammo and better aim. But cool game, and i will come back to play some more!

Well you could do the opposite of finding the fight... so if you say, for instance, if ( getObjectInRange() ) goToward( object ); you could have: if ( getObjectInRange() ) turn( 5 ); or something like that... telling the ants to escort them would certainly be interesting.
