Use the space key, W key, up arrow key, or mouse to go up and down. If you're having trouble, try tapping the button quickly instead of holding it. Don't hit spikes or gears! Yellow portal sets gravity upside down, and the blue portal sets gravity right side up. When gravity is upside down, then you get twice as many points as usual. Portals with arrows change the speed, the more arrows, the faster the speed is. Pink portals change the size of the ship to smaller, and green portals change it back to normal. While you are small, the ship will move up and down faster. --------------------------------------------------------------- Update v0.3.3 Now with more vector!
