Jump Jim, Jump! Jump Jim, Jump!
Everyone in construction has to wear a hard hat. But Jim has to wear one for a very special reason...
Left/Right or A/D = Move
Down or S = Crouch
Up or W = Small Jump
Space = Big Jump (holding it down will increase height)
Get to the top floor. Collect golden wrenches and hard hats (for health). Avoid flying rivets, chihuahuas, traps, and angry aliens.
