sbarisic/RaylibGame — reverse-engineered prompt

Build me a C# .NET 9 voxel sandbox game called Aurora Falls using Raylib cs. I want it to feel like a small first person block world where players can explore floating islands, break and place different block types, swim in water, use tools or weapons, pick up items, and open simple doors.

Please include procedural island generation with grass, dirt, stone, sand, water, glass, and other basic blocks. Add lighting that makes caves and placed light blocks feel different from daylight. Movement should feel fast and fun, with strafe jumping, air control, and swimming.

I also want a simple menu, inventory and hotbar UI, save and load for the world and player, and a headless server plus multiplayer client mode for up to 10 players. Multiplayer should handle remote players smoothly, with server authority for movement, combat, damage, death, and respawn.

Keep the code organized so the shared engine parts, client, server, and tests are separate. Look up current docs online if needed.
