This is a simple, yet interesting game. You have a weird glass orb with a green liquid inside. The orb flies in the air. The green liquid is fuel. While you hold the spacebar the orb goes upwards and burns the fuel. When you release the spacebar, the orb falls down. Using this principle you need to direct the orb where you want it to go. The fuel you have is used pretty quickly, which means that you need to refuel as often as possible. You refuel with organic materials. Pass close to trees, cows and people to abduct them and convert them to fuel. The flying people can be abducted too. The fat guy gives you a lot of fuel and Use space bar to thrust.
