I really loved the concept of this game, and the art is well-done; very much like a comic book, and I love the addition of the text boxes. It took me a few tries to figure out what the 'help' guy did -- I kept trying to click him before the game actually started. I figured out the robot and the elephant on my own, but once I'm down to the robot, the toughie, the alien, and the SWAT guy, I'm lost. I haven't tried *every single command*, but it seems that whatever I choose, it's wrong. Is there a 'negotiate' command...? :p
Anyway, I really do like the game; I think it's an excellent concept that you've executed very well. My only complaint is that once you get stuck with certain characters, you have to redo the entire things over and over and OVER until you either figure it out or get frustrated and give up (which I did, after about the eleventh or twelfth attempt).
Perhaps if you could give subtle hints as to how to take down the more challenging opponents...?
