If you've played SpaceChem, Infinifactory, Opus Magnum, or any of the other engineering puzzles of Zachtronics you'll be familiar with the Zach-like subgenre—visual programming games where you build a system to turn input into output, every level a lesson in learning the tools, and then realizing there are multiple ways to achieve your goal with them.
While Zachtronics shut down a couple of years ago, other developers have picked up the ball and run with it. Last year this resulted in ABI-DOS, a game our Shaun Prescott recommended in his round-up of Steam games you didn't realize came out that week. It's a game about helping digital blocks get from A to B by laying down wires and instructions, a simple foundation it layers plenty of complications onto. The blocks you're shifting around represent code, and sometimes that code can be corrupted. There's also a meta-level where your work on this Assembly Based Interface Deus Operating System is being overseen by a sinister Admin. Spooky.
