Feedback from the experts
Josh Marinacci: It does not work without keyboard controls and I'm on an Oculus Quest, so I couldn't play it. :(
Fernando Serrano Garcia: I couldn't figure out how it works in my VR device (Quest) although on my laptop I was able to move around with my keyboard. Even so, I was not sure what to do there, a little introduction screen would be helpful to understand the gameplay.
Keep working on it! ;)
