This is a bit of a nitpick about your repo and code distribution. It looks like you have a zlib license for the raylib cpp wrapper in your main directory, rather than your own license for the game. Also, you can use git submodules, you don't have to copy all the raylib code into your repo. And finally in the zip you posted it looks like you provide only a Windows executable, but libs for both Linux and Windows. If these are things you are aware of then ignore my comments.
As for the positives. I really like your Makefile, everything is in one place as god intended. Building for Linux was quick, painless, and elegant. Should I have even used Zig for building my stuff ? Have I wasted my life? Seeing Yotsuba was very cute, I eagerly await your future progress!
