I built a multiplayer party royale game using three.js. No login required as part of vibe jam
The game is as the name suggests a knockout based survival game.
3 rounds. 10 players. 1 survivor.
Rounds: 1. Hot air balloon arrow duels 2. Glass bridge (Inspired by Squid games) 3. Falling hex floor
Although it is multiplayer, if you can't find anyone online you can play with AI bots.
