Starfall RPG Builder

Start with a complete, playable hand-painted 2D action RPG, then use a reusable Agent Skill to run, customize and extend it. Starfall Expedition combines manual sword combos with target-aware automatic skills, socketed gems, persistent equipment-slot upgrades and a ten-room forest-ruin adventure.

What you get

• A standard starfall-rpg-builder Agent Skill with task routing, project-specific mechanics and extension guidance.
• Full TypeScript strict, Vite and Phaser source; a ready-to-run production build; all local original artwork and animation/asset manifests.
• One armored melee hero, a complete ten-room chapter, four ordinary enemies, two elites, a dismantlable turret and a three-phase, four-move boss.
• Seven automatic skills, four gem effects, four equipment slots and qualities, persistent slot enhancement, affixes and a separate active awakening.
• Rescue and shrine objectives, queued reinforcements, optional trials, merchant reservations, reward choice, story closure and victory summary.
• Three versioned local save slots, reward deduplication, death/current-room retry, real modal pause, keyboard/touch controls and isolated A/B training.
• A checksum-verifying project-copy helper, a type/test/build helper, 23 meaningful rule tests and five original result screenshots.

How to use it

Install the downloaded Skill in a coding agent that supports SKILL.md, then ask: “Use $starfall-rpg-builder to create a playable copy and adapt its rooms, skills or equipment to my brief.” The helper creates a separate project and refuses to overwrite nonempty folders.

The included build runs locally with Python 3 and a browser. To modify and rebuild source, use Node.js 20.19+ or 22.12+ and npm/pnpm dependencies. A coding agent needs file, terminal and browser access to implement and verify changes. Reusing bundled art requires no image-generation account; new comparable paintings require your own image tool or permitted assets.

Data handling

The bundled game keeps save progress in the browser's local storage. It has no telemetry, account service or upload of gameplay/save data. The included Skill supplies files and instructions to your chosen local coding agent; that agent's own model provider may process the prompts and code you submit under its terms. Source dependency installation connects to package registries. Optional new image generation uses the tool you choose. No external API key is required to play or reuse the bundled artwork.

Verification and practical limits

The baseline was actually operated from a new save through tutorial, all ten rooms, boss, one reward and chapter settlement. Its 23 rule tests, strict typecheck and production build passed. Packaging separately checked the copy helper, non-overwrite behavior, tamper rejection and type/test/build flow on a copied project.

Recorded baseline averages were 59.81 FPS in a five-target skill stress test and 59.07 FPS in a boss test, with a slowest boss one-second sample of 47.53 FPS. Measurements used headless Chrome/Canvas on Apple A18 Pro hardware during captures; they are not guarantees for other devices. Horizontal touch emulation was tested; actual phones and other browsers were not.

Art uses original painted RGBA parts with skeletal animation. Background layers derive from one panorama; foes share some parts; weapon appearance varies by size and quality color. This release includes one chapter and one class, synthesized combat effects without music or voice, and local browser saves. New chapters/classes are extension work, not hidden completed content. This purchase does not include hosted gameplay, cloud storage, custom development services, external image APIs or unlimited AI-model usage.

星隙远征 RPG 构建技能

从一个可完整通关的手绘 2D 横版动作 RPG 出发，用 Agent Skill 运行、修改与扩展项目。包含《星隙远征》首章完整源码、可直接游玩的构建版、原画资源和实际结果图。

包含内容

标准 SKILL.md 技能入口、项目复制与验证脚本，以及 TypeScript strict + Vite + Phaser 游戏。重甲角色拥有三段手动连击、二段跳、突进、自动技能和独立觉醒；首章有十房、四种普通敌人、两种精英、可拆炮台与三阶段四招首领。

包含七技能、四类宝石、四装备槽与四品质、槽位强化、词条、解救/神像/行商/支路/增援事件、唯一首领奖励和章节结算。三存档、奖励去重、死亡重试、暂停、键盘触屏与独立 A/B 训练已经实现。下载保留五张原始结果 PNG，详情上方展示的是实际游戏截图。

使用方法

安装到支持 Agent Skills 的编码智能体后，输入：“使用 $starfall-rpg-builder 创建可运行副本，并按我的需求调整关卡、技能或装备。”复制脚本会校验资源并拒绝覆盖非空目录。

已有构建版只需 Python 3 和浏览器即可运行。修改源码需要兼容 Node.js、npm/pnpm 依赖，以及智能体的文件、终端和浏览器工具。复用现有资源不需要图像服务；新增同等风格原画需自备图像工具或允许使用的素材。

数据使用说明

游戏存档保存在浏览器本地，不包含遥测、账户服务或游戏/存档上传。Skill 向你选用的编码智能体提供文件与指令；该智能体的模型服务可能按其条款处理你提交的需求与代码。安装源码依赖会访问软件包仓库，可选的新图像生成使用你自备的工具。游玩已有游戏与复用资源无需外部 API 密钥。

实测与限制

基线游戏已实际走过“新建存档→教学→十房→首领→领奖→结算”，23 项规则测试、严格类型检查和构建通过。技能包装后另测了复制、不覆盖、篡改拒绝和副本检查流程。

群战与首领实测平均 59.81 / 59.07 FPS，首领最慢一秒 47.53 FPS；仅代表记录的 Chrome/Canvas 测试环境，不保证其他设备。已测横屏触屏模拟，未测实体手机和其他浏览器。

画面使用原创绘画部件与骨骼动画，部分怪物共享部件，背景层由同一原画派生；换装外观通过剑的尺寸与品质色表现。仅首章和一个职业，没有音乐配音、云存档、托管游戏、定制开发或无限模型额度；后续章节与职业需继续开发。
