You are trapped in a twenty-level maze, and your job is to make your
way toward the bottom, and get out alive. Pick up the iron bar and use
it to destroy enemies that get in your way. They will respawn a few
seconds after they have been killed. Go down warp holes to warp to
another part of the level. To exit, you must find the silver key that
will open the locked door. Red balls will float around the screen, and
destroying them will let you obtain a special attack which you can use
to defeat enemies. Boxes labeled ? are scattered around the level, and
destroying these will allow you to obtain armor, shoes, and the key
that you need to exit. Requires 3-D glasses to play.
