About this app

3. Detailed Description (within 4,000 characters)

"let Rust CODING RPG" is a learning app that allows you to learn the Rust programming language through authentic RPG battles.

Core Rust concepts such as ownership, borrowing, lifetimes, and concurrency are translated into a unique world using metaphors of weapons, enemies, and skills, allowing you to steadily understand them while having fun.

■ Four Learning Modes Integrated into One Game Loop

・Read (Book) — Read through the 50-chapter textbook, along with chapter-end quizzes and boss battles.

・See (Lab) — Visualize how ownership transfer, borrowing, and lifetimes work in memory through step-by-step playback.

・Listen (Podcast) — Review chapter content with audio. Choose from three levels: Easy/Normal/Expert (Chapters are being added sequentially).

・Battle (Arena) — RPG battles where you attack by correctly answering code problems. A Full-Fledged Combat System Featuring Combos, Elemental Attacks, and Two-Phase Bosses

■ Authentic RPG Battle System

We've prepared a tense combat system that goes beyond simple multiple-choice quizzes, featuring combos where damage multipliers increase with consecutive correct answers, elemental attacks advantageous in elite and boss battles, and two-phase boss battles where the boss transforms when its HP is halved.

■ Continuous Learning Through Game Loop

Experience points, gold, concept cards, achievements (titles), daily missions, and consecutive login bonuses are all connected in one system, making it easy to accumulate "just a little bit each day."

■ Free Go Language Trial Available

Experience the basics of Go (Goroutines, channels, interfaces, etc., all 5 chapters) as a demo without a paywall.

■ Fully Offline, Honest One-Time Purchase

All learning data is saved on your device and is never sent to external servers. No ads. A one-time purchase of ¥980 (unlocks all chapters of the Rust main story) grants access to all content without additional charges.


■ Recommended for:
- Those who want to learn Rust from scratch with no prior programming experience
- Those who have struggled with ownership, borrowing, and lifetimes
- Those who want to continue learning steadily in their spare time
- Those who want to acquire skills in a fun, game-like way
