About this project
Book Fairy Tales is a browser-based educational game and parent platform. Children explore Tsubaki-chō, a fictional Japanese city in 2D pixel art, while stories and activities are generated to stay fresh and curriculum-aware. This page lists the major tools and creators we rely on so you know exactly what powers the experience.
Development is led by 10k Game Studio. Game design and world details are documented in our internal game design document; the live product will evolve as districts ship.
Website & platform stack
The public site, accounts, dashboard, and APIs are built with:
- PHP — Server-side language (8.3+).
- Laravel — Web framework, routing, authentication, queues, and admin tools.
- SQLite — Default local database; production may use MySQL, PostgreSQL, or another supported driver.
- Vite — Front-end build tool and dev server.
- Tailwind CSS — Utility-first CSS (via Vite).
- axios — HTTP client used in the default JavaScript toolchain alongside Vite.
- Laravel Sanctum — API token authentication for authenticated clients.
- GeoIP2 (MaxMind) — GeoIP2 (MaxMind) for coarse location analytics where enabled.
- Version control; hosting and CI depend on our deployment environment. (Git)
Game engine
The playable game client is built in Godot 4 and exported for the Web (HTML5/WebAssembly), with 2D pixel art workflows. Godot is free and open source.

- Godot — Exporting for the Web
- Godot — License
Game art & audio assets
The visual direction is anime-influenced Japanese pixel art. We use commercial asset packs that must be purchased and licensed on itch.io (or other stores) per pack terms — we do not redistribute raw pack files.
GuttyKreum — primary source for environment and prop art (e.g. stations, shrines, festivals, city streets). Profile and packs: https://guttykreum.itch.io/
Examples called out in our design docs include: train station and interiors, temples & shrines sets, zen garden, festival grounds, arcade and storefront scenes, urban accessories, and related interior tiles — always subject to the license shipped with each pack.
We may add other credited packs or original art over time; this page will be updated when major sources change.
- itch.io — Marketplace where GuttyKreum and many other indie game assets are sold.
Fonts (marketing site)
The marketing and app shell use web fonts served efficiently via Bunny Fonts:
Artificial intelligence
The product vision includes AI-assisted narrative and lesson generation (e.g. curriculum-aligned prompts) so sessions stay novel. Providers, models, and data-handling practices will be described in the Privacy Policy and in-product notices as features go live. We list this here for transparency even when a given build is still static or human-written.
- Anthropic — Claude — Referenced in our design vision for AI-assisted storytelling and lessons.
Analytics
We operate first-party, privacy-conscious analytics for the website. A public summary is available at /analytics.
Open-source building blocks
We benefit from open-source communities. Non-exhaustive examples:
- Godot Engine (MIT License) — godotengine.org/license
- Laravel framework (MIT License) and ecosystem packages — laravel.com
