Arrow keys and WASD to move. Score in your colored goals. You can kinda steal the ball but it might just go in a random direction. You can press space bar for the blue player and C for the red player to gain a speed boost but this uses energy, which regenerates over time. In real soccer, you're penalized for physical contact, but in this game this is obviously impossible. So instead, when running into another player, you both go in random directions and move away. So you can use it as a last resort to prevent a goal, like in real soccer. THIS IS A TWO-PLAYER GAME.
