Opus Magnum is a puzzle-based programming game developed by Zachtronics. It was released for Microsoft Windows, Linux, and Mac in December 2017, following about two months of early access. In the game, the player must assemble a series of machines using various tools and program them to complete alchemy-related tasks. The player can advance with 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 or the smallest occupied area. Opus Magnum is based on The Codex of Alchemical Engineering, one of the earliest Flash games made by Zach Barth prior to establishing Zachtronics.

Runs well on modern hardware.

Sigmar's garden is a great game and you even get an extra dlc attached called opus magnum. Very worth
The game's main drawback is the lack of a performance graph (any cycle/gold metric) of other alchemists. Cost and Cycle graphs are useless because creating the cheapest or fastest mechanism is easy. The challenge is combining these two parameters. This would add some kind of competition to the game. Otherwise a very good game.
Great game, but the last update added something awful: Pop-under advertising! Every single time you open the game now, it pops-under the DLC page on Steam and even starts autoplaying videos. There is no way to disable it. This is absolutely scummy behavior, and I cannot support it. Do better, devs! To be absolutely clear: I REFUSE TO BUY THE DLC UNTIL AFTER THIS SCUMMY ADVERTISING BEHAVIOR IS CORRECTED. I WILL NOT REWARD THIS DESPICABLE BUSINESS PRACTICE!
