I think that the difficulty is just fine on the hardest one, the pistole makes them die quick when it is upgraded, use it more than the flamethrower :)
This game reminds me of N+, great game it still seems different. Need more difficult games on Kongregate, not just time consuming hard, I mean really difficult 5/5, a great game!
I like easy mode, only because you can inflict more damage! So nice that his head will pop, but I would like to kill him better... Do I have a problem?
Great game, could use some polishing, but the concept is a great idea. Also, once you get the hang of thoughts, they are complicated for a reason and that is to allow the user more control over their celles.
This game needs a fast forward button... Just watching peasants get slaughtered is fun, but even more so when it is fast forwarded. 5/5 though, great game :)
