I don't claim to be an expert by any stretch. But have you tried interacting with other creators here on itch?
By that I mean, give feedback on there games, reply to devlogs, just show interest in general.
It would seem most of us here are in the same boat as you, struggling to get noticed.
In my personal experience, I have got the most feedback on my game from people who I have given feedback to.
And I am much more likely to try someones game if they have shown interest in mine first.
Just my 2cents, good luck with your VR games mate, I hope it all goes well for you! :)
