The development of Sudooku was documented in two major phases:
- How I Made My First Game with Godot: Exploring Godot for the first time, learning GDScript, and setting up the foundations.
- Building Sudoku vs The World’s Hardest Puzzle: Implementing the core logic, Note Mode, and the final polish for the Play Store.
- Godot Engine 4.x - Game Engine
- GDScript - Programming Language
This project is open source! I'd love to see the community add features like:
- A Global Timer & Scoring System
- Multiplayer "Speed Solve" mode
