The place is U-chronia, a hazy world that lives in hazy memories of the distant past. OU, a young boy, wakes up in a dried up riverbed without any memories of his own. He meets Zarry, an opossum with a flaming tail, who guides him on a journey to find out his story. Just like a Michael Ende book, “OU” disguises itself as something else – an adventure game – to meet and interact with reality. OU is also a challenge – a challenge to games as a whole.
