Crumbling Dungeons

# Crumbling Dungeons Adds procedurally generated underground combat chambers that spawn naturally throughout the world at various depths. When a player enters one of these structures, a decay timer begins and the dungeon starts to physically crumble block by block from the ceiling downward. ## Gameplay Players must defeat spawned hostile mobs and loot chests before the structure completely collapses and buries everything inside. Each dungeon is a small single-room design with varying layouts, creating quick encounters rather than massive explorations. The decay mechanic introduces time-pressure gameplay without requiring complex systems. Players must decide whether to commit to clearing a dungeon or retreat before being trapped. ## Technical - Uses lightweight block replacement mechanics - Simple mob spawning tied to structure detection - Configurable decay rate - Structures regenerate in new locations over time to maintain exploration incentives Fits naturally into vanilla Minecraft's cave exploration while adding strategic decision-making elements.
