I can't stop playing

Dragon Slayer 2 (http://www.addictinggames.com/dragonslayers2.htm) This has to be one of the most addicting computer games I've played. Its a really simple, yet challenging game.

I have about 100 carpenters :P

I can't get past Level 15, the huge Dragon and his Black Dragons destroyed the castle even though my castle was entirely metal and I had a level 3 ballista. Any tips?
