Multiplayer games and (...) with LiveView
summary
Builds a working AgarX clone using Elixir, Phoenix, LiveView with a single GenServer as the authoritative GenServer world state that ticks (delta time for ~30fps) and resets rounds every three minutes; clients join via QR and use phones as joysticks. Uses nested structs, normalized event routing, and an effects list so logic is pure and testable (property tests via norm/typecheck). Demonstrates limits—LiveView latency and DOM/canvas constraints—but shows the multiplayer demo running and scalable across browser sessions.
