Cathedraticum

Cathedraticum was supposed to be a physics based puzzle game where a Cathedral-sized mechanical computer, the titular Cathedraticum, runs the city automatically. Unfortunately this ended up being a fight against the physics engine followed by rabbit hole on relaxation methods (iterative solvers) and not enough time to build the actual puzzles or even enough different mechanisms (basically just gears and two inputs). You can walk around, connect gears, watch them spin...
