Windmill Software Inc.

Windmill Software was a game development company that developed games for the IBM PC in the early 80's. Windmill games were programmed with a strong underlying knowledge of the hardware, and many of them showed that knowledge with enhanced colors or sound, for example their unique use of the 160x100 16 colour mode on CGA graphics, or their early pulse width modulation of the PC speaker.

Windmill published nine games between 1982 and 1984, Styx being their last one. Almost all of their games were inspired by hits of the times, such as Styx is based on QIX and The Exterminator resembles Centipede with some twists. At least two of their games have had modern remakes, Digger and Styx.

They had quite a success, which called the attention of IBM Japan. They ordered specific ports for their new IBM JX product (similar to an IBM PCjr), so the games could be shipped with each new computer.

They had an unreleased game by the time they stopped making games, due to the small profit margin between the sales and the advertising, which prompted them into abandoning game development and not risking into releasing the new game.

Windmill Software is based in Canada and run by Jo-Anne Kempe. They no longer publish games, but now specialize in software for property management systems and custom management information systems (MIS) software. The original developers of the games no longer work at Windmill Software. The company has recently been acquired.
