We gave every cave background a clean-up, then scattered a bunch of mining clutter across it — coal piles, crystals, lanterns, barrels, minecart pieces, bones, torches. All placed at random positions and random sizes.
• Cleaner cave walls and floors
• 100 random items scattered across the whole map, every run
• Different layout every time you start a game
• Subtle size variation so it feels hand-placed, not robotic
