Silk-road mountain pass: tea-house supply stations must stay on the route or your towers lose potency, and avalanche traps can be triggered on caravans of raiders. Signature: let the avalanche fall while the column crosses the hanging snow-field.
Jade greens with ink-wash mist, terraced peaks, caravan lantern strings, brush-pine accents.
Click, Enter or Space to start. Place and upgrade towers with the mouse and number keys, or by tapping on touch, to stop each enemy wave before it reaches your goal. The HUD tracks lives, cash and wave.
