Hi I am currently buying this for my quest 2, my question is will I get the updates to this for free like is the 8 dollars payment the only payment i ever need to do?

yes, the purchase is tied to your itch.io account. Even if price goes up, you will always be able to download the updates. 

Software is only a few months old.. Plenty of updates to come. Thanks :) 

Ok Great! Already bought and sideloaded it! Sorry if that was a stupid question lol this is my first time on itch io
