Use arrow keys to move Ben. Use W(up), A(left), S(right), Z(down) for Jordyn. 1 key for shooting for Jordyn and 0 key for shooting for Ben. Please read the notes below.
For shooting you have to keep chasing / dribbling the ball and then press the button (button depends for each player. It is mentioned above.) I made it like that because if i didn't add that feature, the ball would go towards the goal even if you are standing somewhere else and kick the air. You will see who is Ben and Jordyn once you play the game.
