I like the concept, the market is insane, have gotten stuck several times with opium and tea trading over 50$ per chest yet nobody will buy it from me for more then 40.
I beat pack A level 20 by putting the orange piece on the right tilter at the very left edge then quickly set the blue V in between the two purple tilters. Big blue ball in the left blue V small blue ball in the small V from the orange piece then threw the yellow box on top. It was touch and go, but, it worked. Kind of an annoying game though.
I love it when they throw back to back grenades and kill everybody in the trench.
By wave 12 they had killed everybody I had, and of course they took out the guys I gave bar's two first...
Luck based? I'm not even a big gamer and did this on the first try getting all badges. Golden Nail+Artillery=win And sweeper, count again :P Looks like ten to me.
