This is one of those classical games where you fly in a spaceship and need to avoid or shoot the obstacles you meet on your way. The original part is that you don't have much fuel. There are refueling points along your way.
How to play?
Controls: Arrow Keys: Movement. Space: Shoot. The longer you hold your ship above such point, the more fuel you get from it. You must always be aware of your fuel level or you'll not get very far.
