It is one of the most famous indie video game franchises. It consists of a cubic open world (made of blocks), in which you can have your own adventure (survival mode), or perform artistic or engineering works (creative mode).
Because the original game has many technical limitations (like everything neatly cubic), this program was created (independent of the original) to animate in 3D.
It overcomes the limitations of the original game, being able to use spheres, pyramids, fluids, curved bodies, etc.
This program is used by some macrophiles to elaborate their fantasies with giants involving the minecraft cube characters.
