Wow, this was thorough, I really liked how large the map was. It really felt like I had a far way to go to collect taxes from everyone which was very immersive! I like the idea of having to do math, but it can get a bit cumbersome as the game goes on. I also think it would be awesome to show the EXCESS amount you've "stolen" rather than just show the oustanding balance as $0 all the time.
Overall an incredible idea and clever take on the jam's theme. Nicely done :)
