Head Soccer is football played by two large-headed characters on a tiny pitch, and this is the Halloween edition: vampires, pumpkins and ghosts instead of footballers. Each character has a special shot, and the goals are the size of the players.
It's built for two people on one keyboard. The physics are silly, the matches last a minute, and every goal is faintly ridiculous — which is exactly the point.
Yes, on one keyboard — Player 1 on the left keys and Player 2 on the arrows. It's the intended way to play.
Each character has a unique powered shot that charges as you play and is much harder to save than a normal kick.
Yes — a light 2D game with nothing to install.
