Doki-Doki Universe is an upcoming game from developer HumaNature and Greg Johnson, creator of ToeJam & Earl. It's due out in December for PlayStation 3, PlayStation 4, and PS Vita, and you can see what it's all about in the story trailer below.
Johnson explains the concept over at the PlayStation Blog:
In Doki-Doki Universe you play the role of a forlorn little robot named Model QT377665 (QT3 for short). You have been abandoned by your human family and are about to get scrapped by the factory that made you, unless you can prove that you’re able to learn more about what it means to be human. On your journey to become more human, you travel across planets and meet all sorts of crazy characters to help solve their problems. You can even take fun personality quizzes where the doctor will evaluate your progress. Along the way, we hope you find something out about yourself too.
