BocchiTheTank131/Codex-Minecraft ? reverse-engineered prompt

Build me a Minecraft inspired voxel sandbox game in C++ that feels like a polished playable prototype, not just a tech demo.

I want a first person world with procedural terrain, caves, rivers, biomes, and streamed chunks, plus a simple but fun survival loop with health, hunger, mining, crafting, farming, and enemies. Please include creative and spectator style play too, so I can fly around and test the world easily. The game should have a main menu, world select, new world creation with a seed, pause menu, save and load support, and basic settings for video, audio, and controls.

Make it support blocks, items, an inventory, crafting, furnaces, chests, mobs, lighting, day and night, and a few basic commands for testing world edits. If anything useful is missing, look up current docs online and fill in the gaps as you build it. Keep it playable and clean, with a simple menu flow and sensible default controls.
