I really like the way that Zachtronics have carved out a niche for themselves as the golden child of programming games. In fact, I almost didn't play Opus Magnum, as I had previously attempted their earlier title Shenzhen I/O. The latter focused heavily on programming and electronics in a way that made my head spin. Thankfully though, Opus Magnum is kind of Zachtronics's offering to the more casual flow-chart designers out there.
