Route water from SUPPLY to every DRAIN — through pipes that stay EMPTY while you build. There's no preview and no undo once the valve opens: trace the flow in your head, commit, and watch your route hold… or leak. Every leak drains the same shared tank. At 0%, the run is over. SURVIVAL — Permadeath against a build clock. At zero, the valve opens itself. Learnable, fixed levels: every scene is the same every run — master them. CHALLENGE — The plumbing is already installed… and sabotaged. Find and fix every fault before you commit. CAMPAIGN — Descend through six facilities. Saves after every level, but once open, the valve NEVER shuts. LIVING MACHINERY — Treatment units scrub fouled water. Gate valves ship shut. Welded faults resist repair. Cracked floors bleed your reserve. Deep levels stack everything at once. KEEP IT PURE — Water fouls as it travels. Run it too far unwashed and it clogs — then bursts. Route through purifiers, or drop portable filters where you need them. WORLD RECORDS — Post your best runs to a live worldwide leaderboard. Three letters, your level, your time. No account, no sign-up. PERFECT ROUTING — Every clear is graded against par. Zero waste earns three stars. Six facilities. Twenty achievements. One shared tank. Hold the pressure.
