About From Zero To Hero

From Zero To Hero is a free book on 2D game development, written by Penaz and published on itch.io. It teaches game development from the basics, and the author describes it as covering the detailed mechanics of building a 2D game. Unlike guides that teach one specific tool, it focuses on tips and techniques that readers can apply to their own games, whether built from scratch or with an existing engine.

The book is offered in several editions, each with code examples in a different language: Pseudocode, Python, C++, JavaScript, Lua, and Rust. The Lua and Rust editions are marked as needing thorough revision. The project is listed as in development, and the homepage notes that it still contains placeholders. Downloads are offered as PDF and EPub files, and the author invites questions, suggestions, and contributions through a discussion board, Mastodon, GitHub, and GitLab. The asset license is Creative Commons Attribution-NonCommercial-ShareAlike 4.0, which limits commercial use of the material.
