After initially denying the request from Zachtronics to have Opus Magnum on GOG, it seems they changed their minds!
About the game:
Opus Magnum is the latest open-ended puzzle game from Zachtronics, the creators of SpaceChem, Infinifactory, TIS-100, and SHENZHEN I/O. Master the intricate, physical machinery of the transmutation engine— the alchemical engineer’s most advanced tool— and use it to create vital remedies, precious gemstones, deadly weapons, and more.
I haven't changed my mind on it since reviewing it, it's absolutely wonderful! If you usually get confused by their games, do give this one a go! Not much else to say that I haven't said already about it—go get it. You can grab it on GOG now. It's also on Steam and Humble Store.
