《附帶導航！一做就上手 第一次的遊戲程式設計》（Game Builder Garage／ナビつき! つくってわかる はじめてゲームプログラミング）是由任天堂開發並發行、專為 Nintendo Switch 推出的入門級遊戲程式設計軟體。由任天堂企劃製作本部（Nintendo EPD）製作，核心理念是讓完全沒有程式背景的玩家，也能透過循序漸進的教學理解「遊戲是怎麼被做出來的」。

以互動式教學為主軸，透過一系列分段課程，引導玩家一步一步建立自己的小遊戲。在學習過程中，系統會以直觀的視覺化編程方式呈現概念，使用名為「Nodon」的元件來代表輸入、邏輯與遊戲物件。只需要拖放並連接這些 Nodon，就能讓角色移動、讓按鍵產生效果，甚至建立完整的遊戲機制。

在教學模式中，會被引導製作多款小型遊戲，例如追逐遊戲、滾球迷宮以及競速遊戲等，藉此逐步理解遊戲設計的核心概念。這種設計讓學習過程不再抽象，而是透過實際操作與立即回饋來建立理解。

除了教學內容之外，也提供自由創作模式，完全依照自己的想法設計遊戲。從角色動作、規則邏輯到音樂與場景，都可以自由組合與調整。玩家甚至可以創作多人遊戲，並與朋友分享自己的作品。

整體而言，《附帶導航！一做就上手 第一次的遊戲程式設計》不只是遊戲，更是一個入門級的遊戲開發工具，它將複雜的程式設計概念簡化為直覺操作，讓玩家在遊玩的同時理解遊戲開發的基本原理，非常適合初學者或對遊戲製作有興趣的人入門。

Game Builder Garage (ナビつき! つくってわかる はじめてゲームプログラミング) is an educational programming software developed and published by Nintendo for the Nintendo Switch. It was designed by Nintendo EPD with the goal of helping beginners understand the fundamentals of game development through interactive, step-by-step lessons.

The software teaches players how games are made using a visual programming system based on small creatures called “Nodon.” Each Nodon represents a specific function such as input controls, logic, movement, or on-screen objects. By connecting different Nodons together, players can create gameplay mechanics without needing to write traditional code. For example, linking a stick input Nodon to a character Nodon allows the player to control movement in a game.

The experience is structured around guided lessons that gradually introduce game design concepts. Players build several simple games during the tutorial mode, including tag-style games, physics-based rolling challenges, and basic racing games. These lessons are designed to make abstract programming ideas easy to understand through hands-on interaction and immediate feedback.

In addition to the tutorial mode, Game Builder Garage also includes a free programming mode where players can design their own original games from scratch. This mode offers a high level of creative freedom, allowing users to customize gameplay rules, visuals, sound, and logic systems. Players can also share their creations with others using game-sharing codes, enabling community-driven experiences.

Overall, Game Builder Garage serves as both a learning tool and a creative platform. It simplifies programming concepts into an accessible visual system, making it an ideal entry point for anyone interested in game design or interactive media development.
