WraithKeel is a vertical 3D ghost-navigation game where you command a ghost ship wreathed in spectral blue flames through unending waves. The core is "center-of-gravity balance"—drag left or right to adjust the ship's center of gravity, countering wave tilt to navigate reef gaps smoothly. Over-tilt causes hull scrapes and durability loss. Collect spirit lamps to maintain shields while avoiding sudden swells and reef clusters. As storm intensity escalates, ship sway amplitude and frequency grow, demanding timely and precise micro-adjustments to keep balance and sail farther.
