# The Flip Side

一款免費的瀏覽器 3D 恐怖遊戲，背景設定在 80 年代的小鎮及其黑暗鏡像版本，你需要在其中尋找一位朋友並將其帶回。它可以在瀏覽器分頁中運行，無需安裝或註冊，並適用於手機和桌上型電腦。

## Description

The Flip Side 是一款獨立的 3D 恐怖遊戲，完全在瀏覽器分頁中運行，免費且無需註冊，適用於手機和桌上型電腦。背景設定是 1980 年代的小鎮及其另一側的黑暗複本，目標是帶回一位朋友；怪物、小鎮和故事都是作者原創的。開發過程中，一個 2D 解謎畫面被重建為 3D 房間。這款遊戲使用 three.js 構建在單一 HTML 檔案中，沒有建置步驟；怪物的骨骼綁定是使用無介面的 Blender 指令碼完成的，所有音樂和音效都是在 WebAudio 中合成，沒有音訊檔案。

## Original post

I built a 3D horror game that runs in a browser tab with Claude Code. Free, no install

I'm one half of a two-person studio in Taiwan. I love Stranger Things, and I wanted to see if I could make something with that feeling: an 80s small town, a dark copy of it on the other side, and a friend to bring back. This is The Flip Side . The monster, the town and the story are my own. Play it here (free, no sign-up, works on phone and desktop): https://play.twinbuilds.com/flip-side/ We're trying to ship one small browser game a day. This was the first. What Claude did Wrote the whole game: three.js, one HTML file, no build step Rigged the monster. The mesh came from an image-to-3D generator as a soup of disconnected shells, so automatic weights failed. Claude wrote headless Blender scripts that build a closed stand-in mesh, compute the weights on that, and transfer them back Synthesised all the music and sound in WebAudio. There are no audio files Tested itself with headless Chrome and screenshots What went wrong The first time the monster appeared, phones stuttered. Cause: adding a light mid-game recompiled every shader. Fix: keep the number of lights constant and precompile on the title screen A 2D puzzle screen inside a 3D game felt wrong, so it was rebuilt as a 3D room What I did: decided what the game is, threw away a lot of versions, and playtested on my phone. Happy to answer anything about the workflow.   submitted by   /u/twinsBuild   to   r/ClaudeGameDev [link]   [comments]
