Orpiment is a rogue-like where the player is not the knight. The player is the audience — specifically, the audience members who support the knight during combat using their own individual skills and abilities. During fights, intervene at any moment by throwing a roast chicken onto the field, deploying panthers, or stealing an opponent's shield when it matters most. The path through the procedurally generated map involves recruiting new audience members after victories, repairing equipment at the blacksmith, upgrading supporters at inns, and purchasing rare gear from merchants. The final destination is the Golden Demon and his four demonic knights.
