Thanks for playing through it! I'll definitely give Chants of Sennaar a go! Great feedback on the country format, this is where I shoudl have gotten more playtesting :)
And one more thing. The sound of explosion you used I have in my game as well. And it is licensed as attribution-4.0-non-commectial. You might wanna add a reference to in on a game page to adhere jam rules)
oh wow good catch, I just hoped over to freesounds and most of my sfx from there, assuming they were fine to use. I didn't credit each of them individually in-game but should probably do that, similar to what I did for fonts
