The Real Ghostbusters, known as Garfield Labyrinth in Europe and Mickey Mouse IV: Mahou no Labyrinth in Japan, is a puzzle/platform game. The story is very simple: Venkman (or Garfield and Odie or Mickey and Mini Mouse) walks over a bridge one day, a tile breaks loose and Venkman/Garfield/Mickey falls down a deep pit, which ends up in a bizarre labyrinth, which Venkman/Garfield/Mickey must escape. There's no other goal apart from that, the player just needs to find the exit in each level. Apart from getting there, the exit must also be unlocked. For the latter, the player must collect all gems in the level.
Gameplay involves avoiding traps and enemies while navigating through levels, solving puzzles to unlock doors and bridges. The player finds a pneumatic hammer at the beginning of the game, which must be used to create paths and access certain areas and items without blocking progress or movement. The protagonist has a health bar and can take several hits before losing a life, but there is also a time limit for each level.
Each level contains various challenges, including finding keys to unlock bridges or open doors, using teleporters, and drilling away blocks. The player must collect all gems in the level to unlock the exit. The game features a password system, where a password is given automatically after completing a level.
The levels are copied from the Amiga game P. P. Hammer and His Pneumatic Weapon, with some changes due to the limitations of the Game Boy. The game was released for the GameBoy on 1st October 1993 in the UK.
