Awesome. It's mind-bending to control two players. The idea of using arrow keys to control one player and WASD to control another is genius. Maybe you can visualize which is which by coloring the explanatory text.
Fair warning: It's a game made for people who excel at ambidextrous tasks like patting one's head and rubbing one's tummy, or juggling Rubik's cubes that you are also solving.
Me and my friends used to play 3 player simultaneously in D-Zone. Obviously we had to be kind with each other about space around the keyboard and about key presses. Still one of the best gaming experiences I ever had.
