I love that you have a README (maybe fill it out, and use the information from your submission page: https://fujiform2023.itch.io/trade-war), and License file (main criteria for open source category).
I like the graphics and sound effects (and the game music too). Interesting concept. I like that it's not just a simple "give stone to both and it's okay". There's some thinking involved which is good. Nice work.
