The objective of the game is simple. You: glowing white dot, hot with destiny. Exit: shining white portal that beckons you ever onward with luminous promises of glory. Click and hold on the white dot with the left mouse button, and then drag your cursor in the direction you wish to shoot. The game handily provides you with a gray line that shows the path you're likely to take, so you can plan your shots better. When you're ready, release the button and watch yourself go zinging across the screen, and plunk yourself within the exit to win the level.
