Yonder: The Cloudcatcher Chronicles is an interesting game. Compared to most games, there's not a lot to do. It's almost impossible to die, there is no combat, and the story itself is rather thin -- involving a creeping darkness invading the islands of Gemea and the need to recover the Sprites that can repel it.
However, you don't really need to pursue the story, if you don't want to. The real fun comes from exploring and interacting with the environment, along with using materials to craft items that help you explore further. There are plenty of side quests too, along with farming elements, that your crafting will help make easier.
Yonder shows off a different side of gaming -- the more relaxed and comforting side that helps you unwind after a stressful day. And that's not necessarily a bad thing.
