Away: Journey to the Unexpected playable on Switch at Gamescom 2017

[JRPGfan]

I was about to say "if thats running on a switch, its one of the best looking Switch games so far".
But then I noticed "PS4 / Xbox One / Switch / PC"

This is most likely the PC build their playing in the video right?

*edit:  Its made by 1 guy alone? jeeze well done dude.
