"While we're extremely excited for all of you to get your hands on Ori and the Blind Forest as soon as possible, we made the decision together with our partners at Microsoft Studios that we'll need just a little more time in order to add a final layer of polish to - what we hope - will be an unforgettable gaming experience," explained the studio in a blog post.
The indie development was first announced earlier this year, during Microsoft's E3 2015 conference with plans of a simultaneous release on Xbox One and Windows PC.
Game director Thomas Mahler described the game to us at the time as a coming-of-age tale about a forest spirit on a journey following a loss. According to the developer, the team spent a large portion of its four years of secretive developing honing the gameplay, which he likens to Super Meat Boy and Metroidvania games in terms of how controls are pushed to the limit.
Likewise, the game will feature continual content streaming with no load times throughout its full 10 hours of content.
