This Axure running man game is using a text field as a control pad with keyup events, users can press a key to start the game with a hidden text panel in the top left corner of the prototype that gets the running man moving. After the initial keyup, the messageboard hides. When the area of the running man is over that of an image map region and you “KeyUp” (press a key), it hides the original running man, and then shows a copy, who jumps, then moves forward.
If you don’t “jump” then when the running man gets all the way to the edge of the platform, there is an “OnMove” event on the man, which makes him fall.
