Head-on-head: bigger wins • Head into body: you die • They run into you: they die
Earn perks fast — first card at length 8! Hover leaderboard rows to see other snakes' perks.
Boss Snake hunts 2nd place! Boss Rush food (magenta) → all snakes mob the boss!
Local 2-Player (same window): press 1 here. P1: WASD/Q/Space • P2: Arrows/M/N
2 Tabs (same machine): Tab 1 → Host (Tab), Tab 2 → Join (Tab). WASD/Q/Space on each tab.
Multiplayer: run node relay.js on one machine — it serves the game AND the WebSocket on port 8765. Everyone (host + others) just clicks 🌐 Join Server and accepts the prefilled URL. One global world, AI snakes always present, up to 50 humans. 🏆 Top Scores fetches the persistent leaderboard.
All same-machine modes need an http:// origin — serve via python -m http.server.
WASD / Arrows = Move • Q = Weapon • SPACE = Dash • Scroll = Zoom
