Nice work for three days, but... I couldn't figure out how the second player was supposed to control anything. I found the ADWS key controls for player 1, but didn't manage to figure out how to control player 2 Also hitting the other player seemed very hard, even when he sat still. Mostly I would just miss him and overshoot. So nothing much happened until the Unity player crashed on me, but that last bit is not your fault Keep going. At least you made something resembling a complete game, which is more than I have done yet.
Thanks! . The controls are: ;'\[ player 1 (red ball) tfgh player 4 (yellow ball) arrow keys player 3 (greed ball) wasd player 2 (blue ball).
