I didn’t see any mention of the Microsoft Store on their website?
Nintendo Switch - on the Nintendo eShop Epic Games Store - for Win / Mac WorldOfGoo2.com - right here, for Win / Mac / Linux, DRM-free
Or are you saying it should also be available on the Microsoft Store? That wouldn’t help my mentioned use case (easy install on Steam Deck and cloud sync between Deck and desktop PC).
EDIT: Also, none of my computers run Windows anymore, so yeah, I couldn’t care less about the Microsoft Store.
