Become an otter in this platformer survival: Three main regions make up the world: you can explore the floating islands, swim in lakes or go deep down into the caves. In each of those regions, there are many smaller places in which you can find interesting items. You will not build your shelter in one place, but you will endlessly wander around the world. The only things that count are your knowledge and what you carry in your backpack. There are many items you can craft, but first, you will have to find ancient scrolls which will show you how to do that and the materials necessary. Completing your library will take you to the most secret corners of the world. The better items you gather, the farther you can go: to the bottom of the lakes (with additional air), caves (with light sources) or to the places guarded by stronger enemies. You will engage in duels with many creatures, using both your agility and rock-paper-scissors combat system. Every sword you get will change your actions' values. All the time, you must watch your health, hunger and sickness points. If they reach their end, you must begin once again. All that persist are your knowledge about crafting and three of the items you possess. Choose wisely!
