Oculus needs to have a different refund policy for "Early access" purchases. Early access implies the game will come with more content or be improved. Paying money for promise of future work should come with recourses if future work is not satifactoryly rendered.
Refund period should start after the game is first played after the update removing "early access" tag has been removed and "early access" phase duration should be limited to 1 month.
I personally purchased many early access games at high prices to later find out nothing was improved and I am left owning a bad game seemingly without any refund options.
