name: Survival_Island
version: "1.0.0"
description: >
  An AI-powered 2-D survival simulation where a HuggingFace LLM agent
  autonomously makes survival decisions across a procedurally-generated
  6000 × 3000 world. Built for the Meta PyTorch Hackathon.

        If you prefer a different model, use HuggingFaceH4/blackbird-7b or
        meta-llama/Llama-3.1-8B-Instruct (the latter may require license acceptance).
