I think you might be missing a dataclasses file in your source code, that's the error its giving
Thanks for trying the game!
The dataclasses module is part of the standard library in python 3.7 and above. I do not think that the game can run with lower version of Python, but you can try to install it with pip install dataclasses. Otherwise, you can download and run the executable directly, it should work out of the box.
