On the image from the “Earth Appreciation Festival” on Steam right now, is the orange Volkswagen Beetle from a particular game? If so, which game?

It has some Solarpunk/Silkgrove vibes, but I doubt it’s based on a single specific game.

Unless its a publisher specific sale/promo, all the images are usually or the main character of the game, or a loose reference to a game, so that they dont infringe copyrights of mixing 2 games in one promo without authorization.
