The tone and art direction of the game sounds so fun! I really enjoy the idea that the game sets place in a museum setting after an ecological collapse has already happened. There could be so many cool themes to play with narratively. Similar to the other comments, I am also a bit worried about the scope of the game. Visuals become very important to establish when it comes to walking sims, and since 3D is what you guys seem to be leaning towards for inspiration that may eat up a majority of the time! Otherwise, this concept sounds amazing and I would love to see how it turns out!
