luanti-org/minetest_game — reverse-engineered prompt

I want a simple, peaceful sandbox game for Luanti that works as a lightweight default base and is easy for people to build mods on top of. It should feel like the classic Minetest Game experience, with basic survival style gameplay out of the box, but no built in enemy mobs, no big story, and no forced goals.

Please keep it stable, clean, and compatible with the current Luanti engine rather than trying to reinvent it with lots of new features. The main value is that it should be a solid, well maintained foundation with the usual core stuff players expect from a basic block sandbox, plus sensible settings and docs so someone can drop it into their games folder and play or start modding right away.

Use Lua and follow the normal Luanti game structure. Include the core game content, configuration files, and any simple menu or utility pieces needed. If anything is unclear, look up the current Luanti docs online and make it match modern engine compatibility.
