Players take part in the challenge by moving about with the mouse, choosing a game option, and finishing it in the shortest amount of time. For player 1, use the up arrow to leap, the left and right arrows to move sideways, the down arrow to pick up a weapon, the Z key to fire, and the X key to switch weapons. For player 2, the controls are as follows: leap or double jump (up arrow), side-to-side movement (left/right arrow), pick up a weapon (down arrow), fire (k), and switch weapons (l). Lucky you!
