Do you like waking up with amnesia and finding out you're a detective caught in something wretched? Do you like the fumbling in the dark against a mystery that eludes you? Do you like Memento and Disco Elysium?
The Ouroboros Case is a quick and lean 48-word RPG that does all this. It's deadly simple to learn but inspires you to make a memorable (hah!) story. The real meat to these good bones lies in the attached 'Case File' replay.
My recommendation is to play the 48-word version before checking out the Neocities link.
