Polytron's Fez is out now on Xbox Live Arcade.
Originally due for release in 2009 but delayed on multiple occasions, the perspective-bending platform game has been picking up rave reviews.
Our friends at Edge called it "pure playfulness" and "an unexpected heir to Super Mario" in the mag's 9/10 review, while GamesRadar gave it the same score, saying: "It's an absolute triumph in creating something new both in terms of its platforming and its puzzle solving; blending together genres in ways we've never seen."
In honour of its release, we've captured the first seven minutes on video. Are you interested in picking Fez up?
