Free Game Stack (pick from 12 free open-source repos, wire them, ship to itch.io)
/free-game-stack
A GameSkill original that turns the popular "12 free GitHub repos, a game studio for $0" list into a plan: one engine and at most one tool per need, chosen from Godot, Phaser, Babylon.js, Kaplay, PixiJS, Matter.js, LDtk, Piskel, Howler.js, ink, Colyseus and butler, with licences checked and a reason for every tool left out. Ships a picker, an ink compiler step, a pack step and a pre-upload check, and Lantern Courier, a tested example using Kaplay, ink, Matter.js and a Colyseus room.

我们测过
在 Node (picker, ink, Matter.js, Colyseus, ship check) + Chrome headless (packed game) 上通过 27/27 项检查（2026-11-03）：能触发、有可运行示例、有截图和自检清单、单一职责、中英文文档齐全。触发检查是把提示词和 skill 描述做匹配，不是真实 agent 运行。

这个 skill 做什么
把 X 上流行的「12 个免费 GitHub 仓库搭游戏工作室」清单变成可执行的计划：从 Godot、Phaser、Babylon.js、Kaplay、PixiJS、Matter.js、LDtk、Piskel、Howler.js、ink、Colyseus、butler 里只选一个引擎、每个需求最多一个工具，并说明其他工具为什么不用。附带选型器、ink 编译、网页打包和上传 itch.io 前的检查。
什么时候用
- 只想用免费开源工具做游戏
- 手里有一长串仓库，不知道该装哪几个
- 给小网页游戏加对话、联机或发布到 itch.io
怎么装
下载本页 ZIP，把 free-game-stack/ 放进 agent 的 skills 文件夹：Claude Code 用 .claude/skills/，Codex、Gemini CLI、OpenCode 用 .agents/skills/，Cursor 用 .cursor/skills/，Copilot 用 .github/skills/，Windsurf 用 .windsurf/skills/。也可以直接对 agent 说：Install the skill from https://gameskill.dev/skills/free-game-stack/install.md
最小示例
原创的「灯笼信使」：迷你网页 2D 游戏，需要音频、剧情、联机、物理和发布。选型器选了 Kaplay（引擎兼音频）、ink（码头管理员的开场对话）、Matter.js（斜坡上的箱子）、Colyseus（接力房间）和 butler，其余七个不用。
我们怎么测的
共 14 项：12 个工具字段完整（中英文）、许可证都是宽松许可并标了核对日期；选型器在 3,840 个 brief 上都满足规则（3D 不混 2D 工具、桌面和手机用 Godot、引擎自带的不重复装）；ink 编译无错、每条选项路径都能开局；Matter.js 箱子两次结果一致并停在码头上；Colyseus 房间里两个客户端看到同一状态，作弊的 99 步被限成 1 步；打包结果通过上传检查，检查器能抓出四类问题；打包后的游戏在无头 Chrome 里用真实按键完成三次送达，无报错。结果在 gameskill/test-report.json。
和原帖的区别
原帖只列了 12 个仓库。这里补上了许可证核对、每个工具什么时候不该用、替代品、选型规则、可运行的示例和上传前检查；没有复制原帖以外的任何内容，12 个工具只链接不打包。

适合
- Making a game with free, open-source tools only
- Turning a long list of repos into a small, shippable stack
- Adding dialogue, multiplayer or an itch.io release to a small web game
不适合
- Deep engine work: use the godot-* skills or pixijs-skills
- Paid engines or asset stores
试试这条提示词
I want to make a tiny browser game with a short dialogue, online play for friends, and put it on itch.io. Use only free open-source tools, pick the smallest stack and show me why.关于这个 Skill
Free Game Stack is a GameSkill original for the moment someone has a list of free repos and wants a game. The agent writes a short brief (web or desktop, 2D or 3D, size, needs), runs the picker over twelve well-known open-source tools, and shows one engine plus one line per need before installing anything. Every tool left out gets a reason, so the project does not end up with three renderers and no game.
The twelve come from a public list posted on X by @iiiichigo_chan: Godot, Phaser, Babylon.js, Matter.js, PixiJS, Kaplay, LDtk, Piskel, Howler.js, ink, Colyseus and butler. All twelve were MIT or Apache-2.0 when we checked on 2026-11-03. They are linked, not bundled.
Lantern Courier, the worked example, uses only what the picker chose for it: Kaplay for the game and its chime, ink for the dock keeper's briefing, Matter.js for a crate on a ramp, a Colyseus relay room where the server clamps each step, and a packed build that passes the itch.io check.

- godot-multiplayer for Godot's own networking.
- pixijs-skills for deeper PixiJS work.
环境要求
- Node 18+ (pick-stack and check-ship use built-ins only)
- For the example: npm ci (kaplay, inkjs, matter-js, Colyseus, puppeteer-core) and Chrome or Chromium

Godot, One Mechanic at a Time (reference folder, grey box, tested mechanics)
A GameSkill original for building a Godot 4 game with an agent in an order that holds up: a reference folder with a style-prompt JSON, a grey box, then one mechanic per prompt in its own script with its own headless playtest, re-running every earlier playtest before the next. Ships templates, checkers for the reference folder and project layout, and a tested 2D example (run and jump, then glide across a gap) whose playtests catch a broken mechanic.
