How can i change the language to german?

There is only mention of Vive in description but i know this is in Oculus Store so why it is not mentioned in store page or does this title not really support Oculus? And if not why is that since it is evident that this works on Oculus?

Whenever i try starting the game on a valve index VR HMD, it tries to start, but then fails and sends me back to home screen. Works fine in Non-VR. Is there something i need to do to make it work in VR-mode?

hello people I was very excited when I got the game and started it then when it loaded I moved the mouse but nothing happened. I can click with the mouse but while moving the mouse the screen doesn't move Please help

Can this game be played without VR?
