To start the game, press the green flag. After you are directed to the main screen, make sure you avoid the green barriers by not clicking. Instead, first press space then click. As the game begins, start to click your mouse anywhere on the game playing to have the bird go up and don't click it to have the bird fall down. Hold down the mouse for a longer, for a more clean "mega jump". The objective of the game is to end up with the shortest score possible after 100 seconds of game play. You beat the game if you can do this with a score of zero! Good luck!
