Hello! I wonder - which engine you're used in development?

How can I contact with developers?

The chance to try before you buy would boost sales. I'm not looking for anything crazy, but maybe a 60 to 90 minute demo period to test the waters would be amazing. I'll use Fallout 4 VR for example ... 30% of the reviews are negative talking of bugs and game glitches. I want to know that this will work before I go spending $60.00 on the game....
