# Slipface

一款免費的瀏覽器越野賽車遊戲，地形是即時模擬的：卡車車輪會在沙地上壓出車轍，並在之後的圈數中持續存在，最多九名 AI 對手會壓出你必須跟隨的路線。遊戲包含七條賽道、十六輛車輛、破壞德比、排行榜以及瀏覽器內的關卡編輯器。需要 WebGPU（最新的 Chrome/Edge，或目前 macOS/iOS 上的 Safari），無需下載或註冊。

## Description

Slipface 是一款免費的越野賽車遊戲，在瀏覽器中透過 WebGPU 執行（無需下載、無需註冊）。地面是模擬而非繪製的，因此車輪會在沙地上壓出真實的車轍，這些車轍在下一圈仍然存在，而最多九名 AI 對手留下的車轍會成為玩家必須行駛的路線。遊戲提供七條賽道、十六輛車輛、破壞德比和排行榜。它還包含一個瀏覽器內的關卡編輯器，建立在遊戲自己的渲染器、地形模擬和卡車之上，關卡以純 JSON 儲存。在 PC 上搭配遊戲手把遊玩效果最佳，也能在最新的行動瀏覽器上執行。需要最新的 Chrome 或 Edge，或 Safari 26 及更新版本。

## Original post

I built a browser off-road racing game with Claude Opus 5.5, Suno, Meshy and ElevenLabs. The ground is simulated and AI trucks dig up the track as they race.

Play it: https://slipfacegame.com/?utm_source=reddit&utm_medium=aigamedev Slipface is a free off-road racer that runs in the browser (WebGPU, no download). I’m a solo dev and built it with AI tools: Platform : browser, desktop. WebGPU required : current Chrome or Edge, or Safari 26+ (macOS 26 / iOS 26). Free, no sign-up. Best with PC and gamepad. Also runs on decent mobile (Chrome on Android 12+, Safari on iOS 26+). Code: Claude Opus 5.5, Sonnet 5.5. The game, the GPU terrain simulation, the vehicle physics, the AI drivers and the level editor are all written with it. Music: Suno. Seven tracks, one per kind of level. 3D vehicles: Meshy, from a picture of the car and its tire, then cleaned up and rigged for the physics. Rival voices: ElevenLabs. Each AI driver has their own voice and callouts. What the AI did and didn’t do: it wrote most of the code and produced the raw assets, but I decided what the game is, picked and rejected the vehicle pictures, tuned how the trucks drive, and play-tested it. The skills that made it repeatable The biggest speedup wasn’t a single prompt. It was writing the boring multi-step jobs down once as Claude Code skills, so a repeat is one request and doesn’t need re-explaining: add-vehicle: takes a brief through Meshy chassis and tire pictures (I approve them), image-to-3D, remeshing to 40k and 10k triangles, compression, the physics preset, the garage entry, rendered tile art and the docs. Sixteen vehicles in, it’s the same checklist every time. add-music: writes the Suno prompts and then wires the finished tracks in, encoded, mapped to levels and recorded in the docs. compress-assets: the web build went from about 35 MB to a 13.5 MB first load (15.7 MB on Safari) because every model, texture and track goes through the same pipeline. release: preflight, commit, push, fast-forward the release branch and verify the live deploy. The part that took trial and error is that a skill has to say what a human must still approve, like the vehicle pictures, or it will happily generate things you never looked at. A level editor, so I’m not stuck with whatever the AI guesses Levels are plain JSON, and there’s an in-browser editor that uses the game’s own renderer, terrain simulation and truck. You drag a ridge or a pit into the terrain and drive it seconds later. Every field in the editor is generated from one schema file, so a new brush parameter can’t exist without showing up in the UI. The game: the terrain is simulated, not painted, so wheels dig real ruts in sand that is still there on the next lap. Up to nine AI rivals race you, and the ruts they dig are the line you have to drive. There’s also a demolition derby, 16 vehicles and leaderboards.
