I recently launched Treasure Guessr, a small web game I made with a friend: https://play.treasureguessr.com
You're shown a zoomed-in "treasure map" (a cropped view from somewhere in the world), and your goal is to find that same spot on a global map. It’s inspired by the treasure maps in FFXIV, and a bit by GeoGuessr, of course.
We built it mostly for fun, and might explore a Steam version with more content for a few bucks if there’s enough interest.
Fun fact: the backend is just a shared Google Sheet queried directly from the React app. Not sure how sustainable that is, but it did the trick for the prototype.
Feedback welcome!
