Moonstone Ruins is a retro RPG game builder kit for turning a focused idea into a playable browser experience. The package combines an original build prompt with the exact HTML source used in the preview, a setup guide and a silent 15-second gameplay recording. Open the source to play the included mission, or attach it to a coding assistant and adapt the game to your project.

Explore the ruin and face its guardian

A fixed-camera isometric ruin introduces a short encounter with a stone guardian. Combat exposes attack, spell and healing commands with HP and MP values. The scene contains an illustrated party, while one controllable combat unit resolves the encounter.

Original isometric stone tiles, ancient columns, layered mountain silhouettes, a floating moonstone, a scarfed adventurer and a low-poly stone guardian. The visual direction is deliberately consistent across the scene: readable objectives, identifiable objects and a small set of coordinated colors. The video shows this implementation in motion, so you can judge its appearance and interaction before working with the files.

What the retro RPG game builder includes

• A standalone index.html containing the game, original Canvas artwork and browser interface.
• A copy-ready build prompt describing the mechanic, visual style, controls and acceptance checks.
• Three example customization directions and follow-up prompts for modifying the supplied source.
• A short launch guide, an editable configuration reference and commercial-use terms.
• A 720 × 1280 MP4 preview, a matching poster and product-specific publishing metadata.

Playable features: Isometric ruin; short exploration; guardian encounter; attack, spell and heal; HP and MP; ending.

Who this kit is for

Narrative-game makers and designers exploring a small retro-inspired RPG scene can use the included implementation as a starting point. It is suited to a small interactive page, a concept presentation or a custom client adaptation. The focused scope makes the rules and code easier to understand before expanding the design.

You do not need a paid AI account to open and play the delivered HTML. A coding assistant is useful when you want to change behavior, redesign the scene or add another mission. Access to that assistant and any usage charges are separate from this purchase.

Start with a working version

Download and extract the package, then open index.html in a current browser. Read the controls, start a manual session and try the objective. The demo button runs the included demonstration, while the separate MP4 is convenient for reviewing the game without opening the source. Use the restart control to begin another run.

When asking an assistant to customize the game, attach index.html together with PROMPT.md. Describe one change at a time, such as a new visual identity or a different mission target. Keep a copy of the original before replacing it. Opening the edited game and trying its objective is the most useful first check after every meaningful change.

Customize the mechanic and presentation

Useful settings for this product include guardian health, attack damage, spell cost, healing amount, character palette, dialogue. The included customization notes point to the relevant state, update and drawing functions. Changing a label or a palette is a smaller task than changing collision rules or adding a new mode; plan your validation accordingly.

Three possible directions are abandoned observatory chapter; forest shrine encounter; desert relic guardian. These are adaptation ideas, not three additional games included in the purchase. The supplied prompt explains how to preserve the core mechanic while changing the theme, so your project can remain coherent instead of becoming a collection of unrelated effects.

Check your edited game

Keep spell and healing costs visible and enforce available MP. Verify both a completed battle and depleted resources after editing combat values. The included scene is drawn in Canvas; it is not a textured PS1 3D engine.

Also test the visible controls, restart behavior and the final state. Review text contrast at the size where you intend to embed the game. If your edited version adds assets or services, make sure the files load from the final deployment location and that you have the rights to use them. The original supplied implementation needs no external assets or account to play.

Clear scope and usage rights

One starter scene and one battle are included. The illustrated companions are not independently controlled party members. There is no inventory, world map, save system or imported-art pipeline.

The included source produces the appearance shown in the preview. A fresh AI generation from the prompt alone can differ, and may need iteration. The kit does not promise identical results across models or provide evidence of testing every coding assistant. The local quality report identifies the checks performed on the included implementation.

You may customize the code for personal projects, commercial end products and client work under the included license. Redistribution of the kit, prompt or substantially unchanged source as a competing template or prompt pack is excluded. The package includes no backend, analytics service, subscription, hosting or ongoing content updates.

Frequently asked questions

Am I purchasing a video prompt? This is a game-building prompt with playable source. The video demonstrates the resulting game; it is not a video-generation service.

Can I use the source without generating it again? Yes. Open the supplied HTML directly. Use an AI assistant when you want help making changes.

Is it ready for my entire commercial project? It is a documented starter game with the scope described above. Your branding, integration and device-specific acceptance checks remain part of your own deployment.
