It's probably been said, but the Surrender feature is bugged. When you quit and go to another level, the game acts as if you never quit. You'll have three of the same heroes on the same screen.
The "difference" series of games are the best out of all others. It combines very realism and surrealism together very well. Also good games to play when you're depressed because they might make you feel better.
