Kirchhoff's Revenge

Gustav Kirchhoff is annoyed because nobody appreciates his circuit laws! You get transported to his secret lair and won't be able to get out until you show mastery! The first-person game 'Kirchhoff's Revenge' teaches the basic concepts of electrical circuits; players need to solve puzzles by assembling macroscopic circuit elements such as batteries, light bulbs, wires, volt meters, and ampere meters. These circuit elements snap together into functional, three-dimensional structures. Moving 'charges' are indicated, so as opposed to real circuit elements, currents are visible. Puzzles increase in difficulty and complexity, while side rooms and pre-assembled circuits offer opportunities to learn new concepts. Game play is strictly based on solving puzzles, there are no dexterity or timed challenges. Once players succeed, they actually get a Schwarzwälderkirschtorte, which they may dispose off as they see fit. The cake is not a lie. The game has been used in physics courses at the high school and introductory college level, and it is now made available as Early Access to the wider community.
