Liquid Galaxy RPG — A Multiplayer 2D Fantasy Game

Liquid Galaxy RPG is a multiplayer 2D fantasy action game built for the Liquid Galaxy multi-screen display system, where a continuous tile-based world spans all LG screens simultaneously. Four players join via a Flutter mobile controller app, competing in King of the Hill (2v2 PvP castle capture) or cooperating in Dragon Raid (4-player boss fight with wave-based enemies). The game is built on Phaser 3 served via Node.js WebSocket — each LG screen opens one URL in Chromium on Ubuntu 16.04 rig. A unique AI Cheerleader powered by the Gemini API runs on each player's phone, delivering private personalized motivational messages via Flutter TTS based on live game events.
