On Planet Gravitron, you control gravity. You can make it pull you to the ground, ceiling or walls, and it's a good thing because you crashed there when your spaceship ran out of fuel. There are thirty levels, and each is an opportunity to collect fuel. In each level, there is a transporter, a platform that opens the transporter door, a box, gravity controls and containers of fuel. Find a way to collect the fuel and get the box onto the platform to weigh it down and hold the transporter door open. Then get to the transporter, which will take you to the next level. Beat all the levels and have a smooth flight home.
