arcraven there are lots more giants on levels after. i t doesn't get harder until after level 5. Farming is of no use if you already have all 3 stars btw. and for brainisdead. Just click wind and hold and draw the mouse in the direction you wanna blow your enemies. Thye won't get hurt unless you get them up and will just take them back. Save for when enemies get last towers to get them back and kill them.
Demon soldier: sir shouldn't we try to take the fastest way home?
Demon leader: No, soldier. We will set up base camps everywhere and kill all our followers. Then we move some miles and does it again. This will of course make our journey harder and harder for each step, but then what are we supposed to do with all the money we can build crazy looking towers for?
