From zero, to a world of your own.
Book-length programming curricula. Every chapter ends in something you can run. Free to read online; buy the offline edition to keep the writing going.
The World
Build a living simulated world from zero
Terrain, water that flows where the ground says it must, plants competing for light, creatures with evolved traits, villagers who remember what happened to them. You type and run every line.
Game Engine Zero
Make games in Go, and the engine they need
Three arcade games first, then the engine underneath them: sprites, tilemaps, a camera, scenes, entities. Written for someone who has never made a game.
Early access means the books are being written. Buyers get every future volume as a free update. The whole shelf, including the planned books, is at /zero. Written by Kryo with AI assistance and a verification pipeline that re-runs every command in the text.
