DoS (every epic needs an acronym) distills the infinite epic sweep of a full-size adventure down into an hors d'oeuvre you can gulp quickly and get on with your life without any of that bothersome textual detail. Roleplaying options include: Explore, open chests when you find them, fight monsters when they show up, and visit the marketplace, where you can buy a fantastically varied array of loot, ranging from wood to tin. That's all you need.
Normally I'd write this game off as an experiment in building a fighting system in Twine, but DoS actually plays so fast it achieves the same addictiveness of a slot machine or a clicker game.
I'm being serious when I say I would probably play this regularly to pass the time if it were extended just a little more to include some more variation: more loot, more outlandishly escalating monster types and more dryly mundane room and treasure descriptions as the player levels up. Throw in three or four random surprise encounter types to keep things interesting, and this is a winner. No, really. I'm serious.
