A tutorial would be nice, and I often need to click on things two or three times before they register. I *think* I'm figuring out the mechanics but it's fairly obtuse. Still, I'm still playing, so it's interesting.
I'm trying to be constructive - this game needs a lot more balance and pacing. Many of the other commentors have said similar things. I hope the next one is a return to the original formula.
Yeah, fullscreen doesn't work, because it's integrated via iframe by Kongregate. Sorry about that! You can play it on our website, where it will also be scaled to your screen size.
What browser do you use? There are some keyboard-related issues in Firefox that I have no clue how to solve :(
