Cosmic Osmo and the Worlds Beyond the Mackerel is a graphic adventure computer game for the Macintosh computer line (Plus, SE, SE/30, II Series, Classic, LC) created by Cyan, Inc. It was published in 1989 and won the 1990 Mac User's Editors' Choice Award for the "Best Recreational Program" category. Spelunx, Cyan's next title, was made with a similar style of gameplay. In 2007, a new Cosmic Osmo game titled Cosmic Osmo's: Hex Isle was released, based loosely on the original's setting but with a more traditional platform game style of gameplay. Game mechanics The game features a point-and-click interface. The player clicks on various elements in a scene to trigger events. To move between scenes and rooms, the player clicks on doors or near the edge of the screen. The game begins when the player enters an animated spaceship hovering in front of the title screen. While inside the ship, he can trigger various events. The spaceship gives the player the ability to visit various planets. Aside from using the ship to move between planets, a complex network of shortcuts exists between planets and scenes. The game, being presented in first-person view, enables shifts from the macroscopic to the microscopic level. Most of the shortcuts are found at the microscopic level: through a water drain or a mouse-hole, for example. Development Cosmic Osmo was created by brothers Rand and Robyn Miller, who went on to form the company Cyan and develop the best-selling adventure game Myst. It was created, and runs, using HyperCard. Animated portions were made using MacroMind VideoWorks, a linear animation program that later became Macromedia Director. An XCMD plug-in enabled VideoWorks animated sprites to be displayed with an alpha mask on top or behind HyperCard's graphic layer. It was first published as simply Cosmic Osmo and required a hard drive for installation. A later enhanced CD-ROM version added more worlds, sounds, and music, and was titled Cosmic Osmo and the Worlds Beyond the Mackerel. Both versions were originally published by Activision, but through a breach of contract the rights reverted back to Cyan. Mark H. DeForest (software engineer and later CTO at Cyan) in December 1995 indicated a colorized version was in development, noting, "...[it] is taking a fair amount of work, but is looking like it will be well worth it." A port of the game was reportedly developed for the SNES-CD, a video game
