Since the first game they've completely overhauled the mechanics making it a 3rd person adventure game instead of the top down previously used. A very bold and smart move, as there aren't many games like this available on mobile devices- potentially creating an iOS/Android kind of Legend of Zelda analog.
As of yet, developers Cornfox & Bros. have neither given a release date, nor have they officially announced what systems the game will release on. We can only hope that Oceanhorn 2: Knights of the Lost Realm will arrive sooner rather than later.
