Protection

xLimbo's sandbox is protected by a set of small, individually toggleable listeners — each registered only when its feature is enabled, with safe defaults on. No single player action can lag, crash, grief or escape the world.

Toggles

• Unbreakable floor — the glass floor can't be broken.
• Void rescue — players who somehow fall out are returned safely.
• Blocked portals — no nether/end portal travel out of limbo.
• No liquids — water/lava placement is blocked.
• No gravity blocks — sand, gravel and similar can't be used for exploits.
• No fire — fire spread and ignition are disabled.
• No explosions — TNT and creeper-style explosions do nothing.
• No mob spawns — the world stays empty.
• No redstone — redstone contraptions are inert.
• No item drops — combined with entity-item blocking and periodic cleanup, dropped items don't accumulate.
• Build-rate guard — an optional cap against lag machines.

Because each listener is registered only when its feature is enabled, disabling a protection removes its overhead entirely.
