This is a 2-Player Game, so two players have to be on the same laptop to play this. First you and your partner need to choose your character (Red, Blue). For the red player hold on w to move, for the blue one hold on the up arrow key to move. The game is simple, when the traffic light is red DON'T move, when it's green MOVE. If you move when the light is red, then you die, meaning you cannot move anymore. First player to reach the doll head wins. Click the green flag to start the game!
If you don't like this 2-Player mode you can always play 1-Player mode by only using one of the players.
