无限程序化生成的探索世界

English prompt

create a new project in my projects folder called "endless-game": an endless, procedurally generated world built with three.js in the browser that i can roam freely and just enjoy. every area should be randomly generated, with surprises everywhere no matter how long i play. it should feel calm, relaxing and genuinely fun, like the cozy, satisfying vibe of a supermarket simulator, but it shouldn't be a supermarket game. i want a really interesting world to walk around in, with entities i can meet and interact with, and really cool graphics. set a clear goal for the project, keep working until you reach it, and play a sound chime when it's done and ready for me to play and test.
