Hadn’t read the description, just looked it up, and yeah, it’s Provence in France, as that’s from where the devs are.

“We are thrilled to finally announce Caravan SandWitch! After two years of passionate development, with its highs and lows and especially strong teamwork, we are really proud of the results. It is definitely a dream come true! We have tried to put as much of ourselves as possible in this game. The scenery takes place in our childhood landscapes of Provence, and all the themes mentioned in the game are really close to our hearts. Knowing that people will follow our work, play our game or even livestream is really exciting!” - Plane Toast
