good, but peaks out in difficulty
excellent concept, and well excecuted, and good fun as well. there comes a point however, when you feel your finger about to break, and take a small rest, only to realise your 30 odd archers can kill almost anything, and you can just poke the heavy tanks, trebuchets and red dudes. at that point, all you have to do is keep reloading and building archers, reinforcing the wall, and the odd fireburst to get rid of a few die hard troops. im on level 23 now, i hope there is more good stuff to come... i'm still playing it at the moment, which both reinforces my point, and goes to show how addictive it is. good job, i hope to see more stuff like this in the future.
