The Manhole runs in black-and-white on Apple's Macintosh line of computers. It was created using the HyperTalk programming language by brothers Rand and Robyn Miller, who founded the company Cyan and would go on to produce the best-selling adventure game Myst.
Release
The game was first released on floppy disks in 1988 by Cyan, Inc. (now Cyan Worlds) and distributed through mail order. In 1989, it was produced for Activision as a CD-ROM version based on the floppy disk game. This version was the first personal computer game distributed on CD-ROM (although there had already been two games released in late 1988 in Japan for NEC's PC Engine game console on its CD-ROM² format). The game was re-released for MS-DOS twice, once in 1992 by Activision as The Manhole: New and Enhanced (including a Windows 3.1 version) and again in 1995 as The Manhole: CD-ROM Masterpiece Edition by Broderbund, which featured the use of color, music, voice, sound effects, and some new characters. Cyan artist Chuck Carter designed all of the color graphics in about three months using StrataVision 3D. In 2007, the game was released on GameTap. As of February 2011, the game is available from GOG.com, iTunes, and as part of the "Cyan Complete Pack" on Steam.
The Manhole was released in Japan for the PC-Engine on March 22, 1991. The Manhole was also released for the FM Towns.
