Seems like a fun guessing game, but the UI wasn't intuitive. I don't know if my first guess was correct, I thought for a while I was supposed to interact with the gray boxes, etc. I'd recommend having some non-dev friends play with it and provide feedback.

Its UI is similar to Worldle (https://worldle.teuteuf.fr/), it might be implicitly assuming you're familiar with it already, in which case the "how close you are geographically" mechanism makes sense.
I don't think familiarity with Wordle helps much. This UI is pretty damn confusing. You type in country names, and then a km value, arrow, and percentage value appears. I have no idea what these signify. Clicking on the boxes brings up a box that gives you information but I have no idea how that information is relevant.
The arrow and distance are from the bad guess to what the answer actually is. So like I guessed Estonia, but the answer was Sweden so the arrow pointed northwest and the distance was some 300 odd km.
Same, and I was incredibly confused by the wordle-style colored squares that briefly appeared. I saw them on the '?' page too, but no explanation of what they mean. I successfully completed the puzzle and still have no idea what those were.
