Make Sail is a physics simulation where the majority of the game is spent designing and redesigning a boat to navigate stormy waters. It has a story, but it is very basic: there is a Tower that once had several Chimes and there were people living on the island with it. These people were happy with the Tower, until one day they set off for distant islands and took the Chimes with them. The Tower got lonely, and a huge storm broke out as a result.
