Hey HN! I built a multiplayer exploration game with an interesting twist: you can only see and chat with players within 100 pixels of you.

Live demo: https://tile.sekor.eu.org

The game features: - Procedurally generated 2000x2000 world (seeded terrain with grass, water, sand, rocks, trees) - Proximity-based visibility and chat (players fade in as they approach) - An NPC "Guide" that walks around and answers questions (powered by local LLM via OpenAI-compatible API)

Tech stack: - Built on Cleoselene engine https://cleoselene.com/ (Rust + Lua scripting) - Server-rendered frames sent to browser via WebRTC/WebSocket - ~800 lines of Lua for the game logic

The proximity mechanic creates emergent gameplay: you never know who's around the next corner, and finding another player feels like a genuine discovery.

Would love feedback on the concept and implementation!
