In Falling Forever, you control an unlucky black silhouette of a fellow who gets dropped through a trap door into a tall empty room. Steer yourself using the [arrow keys], and press [up] to jump from the surface of a bubble. Press [down] if you feel the need to approach your death faster. The [WASD] keys serve the same purpose as the arrow keys. The trick to getting altitude is timing. When you make contact with a bubble, a white circle will start to shrink from the outside of the bubble to the center. The smaller the circle is when you press jump, the further your jump will propel you, but be careful not to wait too long, or the bubble will pop and drop you like a stone. A grade will appear to tell you how accurate your timing is; a high percentage of perfect jumps (hit the button right before the circle completely disappears) will help your score in the end.
