Two-Dimensional Foil adds a weapon inspired by The Three-Body Problem: a foil that irreversibly collapses a 3D area into a flat 2D plane.
Right-click the foil to set the flattening radius (1-1000 blocks) and countdown timer. Place it on the ground, and after the countdown, the area collapses in expanding ripples. All blocks within range are squashed into ultra-thin 2D slices that preserve their original textures. All mobs are flattened into ground decals. Water, lava, and waterlogged blocks are automatically cleared. The effect is permanent and irreversible.
