This is a prototype for a 3-D jumping game. Press the Left and Right arrow keys to move left or right. (You can be either to the left, in the middle, or to the right.) The objective of the game is to avoid hitting walls by going through them. Press Space or Up Arrow to jump. There is a one-second cooldown for jumping. Press the Down Arrow to toggle the Jump Line, a line that shows you when to jump when an approaching wall touches the line.
When the green flag is clicked, the game begins 5 seconds afterwards.
