## Description

The Flip Sideは、ブラウザタブ内で完全に動作するインディー3Dホラーゲームで、無料かつサインアップ不要、スマートフォンとデスクトップの両方で遊べます。舞台は1980年代の小さな町とその向こう側にある暗いコピーで、友人を連れ戻すことが目的です。モンスター、町、ストーリーはすべて作者自身のものです。開発中に2Dパズル画面が3Dルームとして再構築されました。このゲームはthree.jsを使って単一のHTMLファイルでビルド手順なしに構築されており、モンスターのリギングはヘッドレスのBlenderスクリプトで行われ、すべての音楽とサウンドはWebAudioで合成され、オーディオファイルはありません。

## 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]
