If you enjoy survival games, this one is the one you can’t go past! Here you have to survive on a small raft in the stormy ocean. At first, it will be just a sordid board that can barely hold you up. But as you pull more and more materials out of the sea, you can expand it and make it much more voyage-grade. You also have to provide yourself with fresh water, food and weapons to fend off shark attacks. Good luck!
