Today's update adds a new in-game "application" called conceptSPEC that allows you to create your own puzzles and upload them to the Steam Workshop. You'll need to learn a little Lua to design your own puzzles, but fortunately you're all experts at deciphering esoteric programming languages!
Also, we fixed a bug where traces would sometimes light up as if they were connected to a pin when they really weren't. If you were seeing weird behavior in your logic-heavy circuits, this might have been part of the problem.
