The honkin' success has already made a splash on the Nintendo Switch, but that's far from the end for the game.
Untitled Goose Game has been one of the hits of the year so far, but it turns out the journey isn't over for House House and Panic Inc., as revealed in an FAQ on the game's site, which says that we can expect it on "other consoles". That said, there's nothing to announce on this right now.
Right now we can get it on PC and Mac via the Epic Games Store, or on the Nintendo Switch, but we can expect to see it on Steam, Itch, and the Mac App Store in late 2020. We're also told that there are no plans for a physical release right now.
