Thanks :) I cannot wait till I'm done with core gameplay mechanics as then I'll start adding more actual content. And a very big step after that will be adding narrative.
For Quest? The best way is to do it via Sidequest ( https://sidequestvr.com/ ). There are instructions what you have to do (you need to setup a developer account, switch your Quest in developer mode and then install games via Sidequest on you computer or commandline using adb). Please check that website.
