Thanks for pointing out the issues on Linux! I will disable Linux downloads, since you're not the first one to point out these issues exclusive to Linux.
Unfortunately there isn't really anything in particular I can do to fix them because Unity is responsible for compiling the project for various OSes, and the only ones that I can test are MacOS and Windows anyways. The only thing I can try is to upgrade my Unity compiler.
Thanks again for your help, and I'm glad you still enjoyed the game and the idea despite the issues you faced! 😊
