How To Beat The Game

To beat the game, you need to build a boat from the factory(factory crafting recipe can be found in the workbench). After you have the boat, go up to the ocean surrounding the island and click. Then, you will have sailed away from the island, thus beating the game. This isn't the hardest or considered the "best" way to beat the game, and results in the game telling you "You escaped, but the monster still lives..." with a picture of you in the boat, leaving the island behind. If you want to make the game more difficult for yourself, try to beat the boss(found in a corner of the underworld) and then escape the island. This would give you the harder to accomplish ending, thus being the "better" ending, and would tell you "You escaped in a boat full of treasure" with a picture of you in the boat full of the rubies you got when you destroyed the eel.

You can also try speedrunning the game, where you time yourself and see how fast you can either escape the island in a boat or kill the boss. If you wanna go for fastest in the world, or maybe you just wanna watch someone beat it really quick, there's a leaderboard on https://www.speedrun.com/stranded_isle/full_game that'll let you watch other people run the game.
