This is such a fun game, especially for geography nerds, it's incredible how much work you put into it!
Some things that I thought of are-
1. In the top down camera angle, I think it would be nice if you could easily freely rotate the camera
2. The timer was quite confusing at the start of my playthrough, tbh I didn't realize that it existed until it told me that time was up
3. A way to scroll in on the map without having to click zoom in or zoom out (either with a mouse or maybe arrow keys) so it'd be easier and allow for more options
4. This is so cool omg
