Psychonauts in the Rhombus of Ruin has launched today for PlayStation VR, and developer Double Fine Productions has released a documentary-like video explaining how the game was made and some of the challenges it faced when creating the game.

"Making a VR game is really exciting," company founder Tim Schafer said. "It's like traveling into a strange and mysterious new world. And who knows more about traveling into strange, mysterious new worlds than the Psychonauts? So we're happy to have Raz and friends along with us on this new adventure."

Players take on the role of Raz, who has become a full member of the Psychonauts team, which is trying to rescue its founder Truman Zannotto. The video details design decisions, how the mental powers work in VR, addressing possible motion sickness, and even how some of the story elements were created.

The game is designed to bridge the gap between the original 10-year-old game, and the upcoming Psychonauts 2, which had a highly successful crowdfunding campaign and recently grabbed an additional $8 million investment from Starbreeze.

Pyschonauts in the Rhombus of Ruin is selling for $19.99 on the PlayStation Store.
