I’ve been working on Meow Story Engine, an extremely lightweight proof-of-concept interactive fiction engine designed for AI-generated “card-based chapters + multiple endings” story simulations. It’s open source (Apache-2.0).

The game script is defined using JSON files, making it straightforward for LLMs or tools to generate story content automatically.

Key features:

Card-based Events: Each chapter consists of 16 event cards.

Multiple Endings: 4 normal endings + 1 hidden ending.

Branching Interactions: Player choices affect the story’s direction.

Resource System: Track stats like stamina, satiety, and energy.

Hidden Routes: Specific conditions unlock side plots.

I’d love to hear feedback from anyone working on interactive fiction, game engines, or AI-driven storytelling systems.
