Ash Plateau

Welcome to Ash Plateau, a volcanic highland where the only warmth comes from geothermal steam — and every greenhouse depends on you.

Steam flows from a single main line into a branching network of glass domes. Each dome has its own pressure gauge, and crops only grow while the needle stays inside the green zone. Tap each valve wheel to open or close that branch, but remember: the total steam supply is limited and rises and falls with the mountain. Open one valve wide and the other domes starve.

Features:
- A unique pressure-balancing puzzle: every valve affects the whole network
- 8 sectors with rising difficulty, tighter steam budgets and stronger fluctuations
- Leaking pipes that constantly bleed pressure and demand spare margin
- Mixed-crop sectors where each dome needs a different green zone
- Blowout stakes: hit the red line and steam erupts, scorching your crop
- A supply depot with six upgrades: insulated pipes, steam battery, wideband regulators, ash fertilizer, safety valve and leak sealant
- Fully synthesized industrial soundscape with valve hisses and eruption rumbles
- Harvest coins for every cleared sector and unlock the whole plateau

Keep the gauges green, ride the pressure waves, and bring the harvest home.
