The flashback of a group of boats and one boat gets separated from the rest, as there is a storm, therefore it is now lost. The boat floats far away from the others and is left in the middle of the ocean.
It is now close to night and the player must now survive 2 weeks at sea by themselves before the rescue team will find them. The player then starts at level 1 the next day.
The first level is finding a small island at sea. The player comes across their first bad fish, learns how to fish, learns the basic contols and gets to know the objectives and scenery of the game.
Levels 2-7 (5 levels) include new locations, new object creations and new fish to find. The way to gain points is to create new tools/objects, killing, selling or catching fish and completing levels.
Levels 7-12 (5 levels) includes different weathers and temperatures meaning that new objects have to be created, things such as clothes, to survive.
The last 3 levels is where the player must survive by themselves through the day and night, unkonwn to the player is the weather, temperature and chance of death by the bad fish. The whole way through the items created save but in these levels they would need to create new items.
