thecodeofnotch/rd-132211 — reverse-engineered prompt

Build me a small Java recreation of the early Minecraft pre classic rd 132211 build. I want a simple playable block world where you can look around, point at blocks with the mouse, place tiles, destroy tiles, and see a flashing white highlight on the face of the block you’re aiming at.

Please keep it close to that old prototype feeling rather than making it modern or fancy. The main thing is the basic tile placing and breaking loop. Add a way to save the level when I press Enter, so I can come back to what I changed. It should run from Gradle with a simple run task.

Use the existing project setup if there is one, and keep the code easy to understand. If you need details about the original rd 132211 behavior, look up current references online and match the spirit of it without overcomplicating it.
