Opus Magnum is a puzzle-based programming game developed by Zachtronics. It was released for Microsoft Windows, Linux and macOS in December 2017, following about two months of early access. In the game, the player must assemble a machine using various tools and program those tools to complete alchemy-related tasks. The player can produce any working solution to each problem, but is challenged through leaderboards to produce a machine that does the task in the shortest time, with the lowest cost of materials, and/or the smallest occupied area. It was based on The Codex of Alchemical Engineering, one of the earliest Flash games made by Zach Barth prior to establishing Zachtronics.

Gameplay

After placing manipulators, the player must then provide each manipulator a set of commands that take atoms from input spaces and drop the proper completed material into the target output space; an early puzzle demonstrates how one turns lead into gold. Manipulators can have individual programs, and each run simultaneously once the machine is started. The goal for most puzzles is to deliver a fixed number of target output products, thus testing the machine's operation over several cycles. Should the device encounter a physical collision between atoms, the device will stop and require the player to readjust the machine.^[1]

Once a player has successfully demonstrated a device that completes the goals of the puzzle, they are ranked with all other players based on three factors: the speed of the device, the cost of the device, and the total area that the device takes. Player can then attempt alternate solutions that improve in any of these areas. Completed devices can be exported into a animated GIF to be shared on social media.^[1]

The game is structured through several chapters, providing the player with multiple puzzles they can work on and come back to as needed, though all puzzles within a chapter must be completed to progress to the next. The game includes Steam Workshop support to allow users to supply their own puzzles, with the game only accepting puzzles that the user has shown possible to complete on their own.^[1]

Development

As with several of Barth's recent titles, he opted to release a near-completed version of the game on early access via Steam prior to issuing a full release. The game was first put onto early access on October 19, 2017.^[5] It was fully released on December 8, 2017. Barth noted that while he normally has sold his released titles on GOG.com in addition to Steam, GOG would not sell Opus Magnum for undisclosed reasons.^[6] According to GOG, the game did not pass its internal curating system which they state "We take into consideration many other factors than just the actual game itself—the reviews we provide for example do not review the game in general; so like an objective game review like on PC Gamer or what not—but we do it from the angle of our entire user-base."^[7] However, by January 31, 2018, GOG began offering Opus Magnum for sale, saying that in part, this change was influenced by fans of the game that wanted to buy it through GOG.^[7]

Accolades

The game was nominated for "Best Puzzle Game" in IGN's Best of 2017 Awards,^[8] and for "Best Indie Game" and "Best PC Game" at the 2018 Golden Joystick Awards,^[9][10] and won the award for "Excellence in Design" at the Independent Games Festival Awards, whereas its other nomination was for the Seumas McNally Grand Prize.^[11][12]
