The Stone of Sisyphus

A fantasy adventure where you can create your own characters, choose from a wide inventory of weapons and armor, and use freeform input combined with making choices to explore a dungeon.

This is a dungeon crawl game - equip your character, enter the dungeon, fight monsters and win treasure.  Traps abound as well.  Many events are random.  You can save your character (assuming he survives) to use in later episodes.  This episode is touted as ‘a thinking man’s adventure’.
