Theme Park Mystery

Theme Park Mystery is an adventure video game developed by Brian Howarth and Taeman Irmak released in 1990, for the Amiga published by Konami. It was also released to the Atari ST and MS-DOS later in 1990. The game features themes and activities surrounding a haunted and gruesome amusement park.

Gameplay
The player is tasked with journeying through four worlds, whilst collecting keys, potions and other ingredients to solve the cause of the players uncles' insanity. The player has recently inherited a new property, a Magic Canyon Theme Park. The park has become abandoned, and infested with enemies from ghouls to apes.

Starting at a Zoltan Wishing Machine, the player continues through four zones of the theme park - Dragonland, Dreamland, Futureland and Yesterdayland. Hidden within these levels are a total of eight boss fight with Demons, each of which require being brought back to the Zoltan machine.

Each of the four worlds has its own gimmick and control scheme. Yesterdayland is the game's hub world, where the player can access the other worlds and the rest of the game via monorail. Dragonland has the game play as side-scrolling platformer, Dreamworld is set inside a dream, on a chess board and Futureland is an on rails shooter; where the player is firing bullets atop a rollercoaster. Aside from Yesterdayland, the remaining worlds can be visited in any order.

Development
Theme Park Mystery was created by British development company Joined Up Writing Software, a group made up of Brian Howarth and Taeman Irmak. The development company would only ever go onto create this one game, with Howarth moving shortly after to the United States. He would continue to work on games working for CinemaWare; USA until the company dissolved the following year. Howarth would spend time working on this game, whilst he was also working for CinemaWare. Irmak created the artwork, whilst Howarth programmed the game.
