Nebulous: The Game of Incomplete Entities

From publisher description:

Presenting Nebulous: The Game of Incomplete Entities, an abstract role-playing game for two players. What is an ‘incomplete entity’? That’s a good question. An incomplete entity is an ill-defined being that seeks to define itself and gain an identity.
In nebulous you play as such an entity, defining yourself through your experiences with the ultimate goal of determining who (or what) you are?
In a game where you could be anything, what will you be? The only way to find out is the play.
