Use the space key, W key, up arrow key, or mouse to go up and down. Yellow portal sets gravity upside down, and the blue portal sets gravity right side up. Also, when gravity is set to upside down, then you get twice as many points as usual. Same with mini wave. But with both you get four times as many points as possible. Secret Coins give you 10 points regardless. Press "M" key to turn off music. Don't hit spikes or gears! --------------------------------------------------------------- UPDATES: 0.2 added speed portal
