It's Go-kart 1 against Go-Kart 2. Go kart 1 uses a,s,d and w to move. Go kart 2 uses the direction keys. The go kart with the paintball gun can aim and shoot with the mouse. Every time he hits the second go kart (with no gun) that go-kart loses a bit of life. when the go-kart with no gun changes to a fail picture he loses and his point-counter stops. Every 10 seconds go-kart 1 can jump to any corner with the q,e,z and c keys. Go-kart 2 can only lose a bit of life every 5 seconds. Good luck!
