Oceanhorn 2: Knights of the Lost Realm
Oceanhorn 2 is, as its name suggests, the second part of the zelda-like from Cornfox & bros. released in 2013. He abandoned isometric 3D graphics to opt for real 3D, reminiscent in his Zelda style: Skyward Sword (or Breath of the Wild to a lesser extent).
The title relates ” the end of the world in the kingdom of Arcadia […] the tragic tale of two eternal souls” You play a hero who left on an adventure to find a chest … but things will not quite go as planned.
It is certainly the flagship game of the service for the moment, but beware: the controls are not necessarily obvious at first (it gets better over time) and it is thought of as a console title, so it is better to have a moment before you when you start a game.
