no insult meant, I just meant it's not something I'd buy unsure it would work. (I don't know what itchs refund policy is, if any) Hopefully someone will buy it and report back that it works.
I don't expect you to buy one to test, of course.
2d games appear as a floating window.
If it works on GearVR as 3d, it probably works in 3d on Quest, then the next biggest question is does it work with the controllers... That's often an issue.
There are lots of Quest owners on itch.io looking for games now (Sidequest is gaining popularity, but some of the listings on it require visiting itch to purchase the game).
