The Codex of Alchemical Engineering is a puzzle game about programming “manipulators” to move, transmute, and bind alchemical “atoms” into complex compounds. If you’ve played SpaceChem and this sounds familiar to you, it’s because this is the game that inspired it!

A few notes about the game:

  • After completing a level, your progress is saved so long as your Flash “cookies” aren’t deleted. Your design, however, is not; if you want to keep your design, you must go to the Save screen and save the text shown there (I keep my solutions in a text file on my desktop). You can reload a saved design by pasting the design code into the Load window and pressing the load button.
  • The music playing is Evan’s “Rever… Peut-etre…”, which you can find here on
