Moonlight Madness, developed by John F. Cain, is an arcade adventure game in which players control a boy scout.
Players must navigate a 43-room mansion in order to obtain 16 keys and a combination before running out of time. These unlock a safe containing the pills needed to save the mansion owner's life. It is necessary to jump onto platforms and evade enemies in order to progress. At the start of the game the player has three lives; a life is lost should the boy scout fall too far or come into contact with one of the mansion's servants or traps. Rooms contain doors that can be entered to move around the mansion, as well as push buttons and hazards. Pressing buttons can result in lifts being activated, platforms appearing or in an enemy appearing. One of the mansion's rooms is a corridor of eight doors with a large pair of eyes above them; this room acts as a maze. A tune is played continuously during play, but can be toggled on or off.
The player character, a boy scout, has approached a mansion looking for work during Bob a Job week. The door is answered by an old man wearing horn-rimmed glasses—the owner of the mansion. The man, a mad scientist, expresses surprise that the boy has managed to get past the guards and booby traps in the mansion's grounds. As the boy scout explains the reason for his visit, the scientist collapses, asking for his pills. At this point the game begins. The player must gather the 16 keys needed to unlock the safe and retrieve the scientist's pills before he passes away. During play the boy scout must negotiate the mansion's rooms, avoiding hazards and the mansion's staff, who have been told to protect the inventions within the mansion, using lethal force if necessary. The staff are unaware of the boy scout's purpose and will attack him should they come into contact.
