The Codex of Alchemical Engineering: Magnum Opus Challenge
The Codex of Alchemical Engineering: Magnum Opus Challenge - Yes, that's exactly what cerebral puzzler The Codex of Alchemical Engineering needed. A longer title. Anyway, there are fifteen new brain-teasers here, created by both the author of the original game and its fans. When Zach (the author) says that this expansion may destroy the minds of those who haven't finished the first game, do not take his words lightly.
And while 15 extra levels may not seem like much, these puzzles are extremely challenging and each one will likely take you hours to complete. We recommend you play some of Zach's other games in the Zachtronics series of games first before tackling this one. You may also want to go to your local university to get an engineering or computer science degree if these games appeal to you. :)
