From the README:
Cubyz is a 3D voxel sandbox game (inspired by Minecraft).
Cubyz has a bunch of interesting/unique features such as:
Level of Detail (→ This enables far view distances.)
3D Chunks (→ There is no height or depth limit.)
Procedural Crafting (→ You can craft anything you want, and the game will figure out what kind of tool you tried to make.)
