Your game is pretty cool. For me the gameplay feels a bit too slow. The graphics, theme and performance are great though. All-in-all a good game for a jam. In case you want to keep working on the game, I would suggest adding something similar to a quest system or some clear incentive for the player to follow.
Also a fan of the technology stack you used. We used rust for server and godot with gdscript for our client and now have performance unsuitable for mobile. Therefore I am currently creating a new client right now, also using SDL2 and Rust only, while minimizing dependencies too.
