Use the left and right arrow keys to control. Click space to punch. Welcome to Teamwork Nation! Where you and your friend try to win against the enemy's that will spawn. Unfortunately, this is a demo. So your friend can not attack, and there are a couple bugs. So, I hope you enjoy! The red enemy is called 'Attacker'. You need to punch him before he attacks you. The purple enemy is called 'Stealth Attacker'. He jumps up from the ground to attack you!
