From the description: An ultra-lite, solo, no-prep dungeon crawler! A system agnostic rule set that can be used as a stand alone one-shot or as a plug in for other OSR games. As a stand alone game, Harper's Quest uses a rogue-like mechanic that lets your future generations fight through the dungeon with acquired heirlooms and some extra gold to help your lineage along. Why they're in the dungeon and what they're after is entirely up to you. If you're short on time and want to just relax and roll some dice with some lite OSR rules, this game is for you. At least 3D6, 1D8, 1D10, 1D12 and 1D20 are needed. Or an app that rolls dice.
