some sort of heal between battles that also raises threat as an option, having the leather clad guy not ALWAYS escape if attacked (sometimes I don't have enough gold for it to be worth it) and maybe a hero the specs in defence, like they get armor and maybe their special is thorns.
IMO rezzing in battle should either heal more or not take up a turn, you already have to get close enough, and then they just get 1-shotted, if you are up against multiple ranged enemies you basicly die on the first turn unless you are lucky
getting tons of vip tokens when I'm not a vip is annoying, especially when I'm trying to get mats for synth items, also runes feel useless, they dont sell for much and the limited uses makes me not bother, you should change them to bonus powers or into tokens to buy class specific powers from a store
ok so my only beef are some graphical issues, if you zoom in full screen, if you exit full screen or get pul;led out by a cutscene, part of the screen gets clipped, only fixable by restarting the page
expert zombie defense is too hard now, I got 4 straight 5's after falling behind a little bit and then extra combos from falling, still lost, barely did any damage
either slow it down or make combos kill more zombies
ok well, winning strategy: mass ninja, couple of bombs and like 6 snipers for any lead/camo baloons that your ninjas can't hit, add in banana farms and a couple radar towers so your ninja can hit anything later
