About Orthanc

This game is a faithful recreation of "Orthanc", one of the first graphic dungeon crawl role-playing games developed for the University of Illinois Urbana-Champaign's PLATO computer in the 1970s. The original was played on a PLATO terminal with a keyboard. (The PLATO version of "Orthanc" was inspired by "pedit5", which you can learn more about in Wikipedia.) The original PLATO terminals used plasma panels only capable of displaying orange and black. There is no sound. This implementation uses the touchscreen for all gameplay. You are an adventurer gaining experience and treasure by defeating monsters. Orthanc is easy to start but hard to put down.
