Left-click to place, right-click to break (or use the mode button). Pick a block below or press 1–9 (0 = Water, L = Lava — both flow!, O = Obsidian, P = 🟪 Portal). Placed liquid is a source; break the source and its flow drains away. Water hitting lava makes stone/obsidian! Use Drain Liquids to clear it. Your build auto-saves. Surround 🟪 Portal blocks with Obsidian to light it — it flashes & spits sparkles! 🌍 Dimensions: place a 🟪 Portal block and right-click it to warp to the 🔥 Nether; place an 🌌 End Portal block and right-click it for 🌌 The End — right-click a portal over there to come home. Each dimension keeps its own build. Click a 🥚 spawn egg then click the world to drop a mob — animals wander, but 🧟 zombies, 💀 skeletons & 🕷️ spiders hunt your cursor (and hop over walls)! Mobs caught in lava catch fire & despawn. Use the 🚫 Mob Eraser (then click a mob) or ❌ Clear Mobs to remove them.
