Build, craft, and survive in fully customizable voxel-based worlds for PC & Mobile.
Voxel Building, Crafting and Survival System is a complete, modular framework that allows you to create interactive voxel environments with block placement and destruction, inventory management, crafting mechanics, and dynamic world simulation.

The system includes procedural world generation, saving and loading, a day–night cycle, weather systems, and a basic Creature AI system. Designed to be flexible and extensible, it provides a solid foundation for survival, building, or sandbox-style projects. Everything is structured for easy integration and customization, allowing you to focus on expanding gameplay, adding new mechanics, and shaping your own unique voxel experience.
