Marburgh is a fairly straightforward dungeon crawler.
You are part of an adventuring family, attempting to rid the land of the evil monsters that have ransacked your town. You play as each of 3 siblings until their death or until the game ends. If all of the siblings die, the game is over.
Marburgh started off as a project to build a very simple game in under 10 hours and has grown into a full fledged game. It is an attempt to evoke the old school BBS door game feel of Usurper, Exitilus and Legend Of Red Dragon while incorporating some newer game mechanics.
