Built a multiplayer Pac‑Man clone called Mungo man using Node.js + socket.io and Express, with a MongoDB ring buffer holding game state per process so each game lives in one process. Client uses canvas and SoundJS; Acqupa/aquepara provides retro game scaffolding. WebSockets (TCP) causes jitter because of ordering; WebRTC datachannel with SCTP unordered messages is recommended. Latency examples: 20 ms ping → ~40 ms roundtrip → ~25 FPS; 135 ms ping → ~270 ms → ~4 FPS. Dedicated servers and careful memory use avoid V8 GC pauses.
