Level Block Mod locks your survival world inside a tiny boundary and asks you to spend XP levels to expand it block by block. You start inside a three-by-three space and walk toward the border whenever you want to buy new territory. Each full level unlocks one vertical column from sky limit down to bedrock. Friends on a multiplayer server share the same unlocked ground across every dimension while paying with their personal levels.
Features:
- Shared World Space: Players in multiplayer share every unlocked column across the Overworld, Nether, and End.
- Full Column Expansions: Walking into a border spends XP to open a full vertical column from bedrock to sky height.
- Harsh Death Penalty: Dying deletes your inventory and worn armor by default to keep challenge stakes high.
- Three Dimensions: Features separate starting zones of 3×3 in the Overworld, 5×5 in the Nether, and 3×3 in the End.
- Custom Visual Outlines: Custom borders and corner markers trace terrain contours through hills and deep caves.
- Progress Milestones: Grants custom advancements when reaching 1, 10, 50, 100, 500, and 1,000 purchased columns.
- Sneaking near borders lets you build or lean out without accidentally spending levels.
- Boundary recovery checks keep you safe from falling out of bounds when waking up from beds or leaving seats.
- A sidebar displays your current level balance while you collect resources and wander around.
- World progress and challenge timers remain safe after server restarts or game pauses.
