Mickey has fallen down a shaft and has to work his way through an underground maze using his trusty pneumatic hammer and wands he finds along the way so that he can collect enough stars and make his way back to the surface. Mickey Mouse IV: Magical Labyrinth is a 1993 action-puzzle video game developed by Kemco and published in Japan. The game is an unauthorized port of P. P. Hammer and his Pneumatic Weapon, featuring simplified sprites and near-identical level designs. The gameplay is similar to two other games also developed by Kemco, The Real Ghostbusters published by Activision in North America which features 10 extra levels, and Garfield Labyrinth published by Kemco in Europe.
