Cast-Off - The Sailing Simulator

At a glance: Cast-Off is a small sailing simulator that tries to simulate the main effects that occur during sailing on the ocean, such as the interaction between the boat and the waves and the influence of the wind on the sails.

Image Title

Gameplay informations: The sound of the howling wind depends on the strength of the wind-see gameplay instructions for how to change the strength of the wind. The player can steer the boat. Please keep in mind that sailing against the wind is physically impossible and result in a speed of 0 knots.
