The new update is cool because it adds new upgrades and this whole idea of spending AIs, but I'm really hoping for a faster way of buying soon. Resetting and having to buy 600 of everything, all managers, and all upgrades is a lot of clicking if you have the money for it. *Crossed fingers for BUY ALL button next patch*
Instead of making one of the lesser mobs Liquid Samurai.. You should have made the Samurai boss (the one who is platinum at Starcraft) LiquidSamurai. ;)
Wizards are the best class... Their "Frighten" skill can make bosses completely useless and make them run around while your henchmen beat him up as you cast high DPS spells.
I didn't find normal hard at all.. you just have to be smart and not send all your people out when there is a zombie attack... No doubt that hard + would be pretty crazy.
