Thanks for the question!
Yes the file size is bigger than I would like too. This seems to be a limitation with the way I convert from Python code to a .exe (Pyinstaller). So most of my games (the ones written in Python), even relatively simple ones, have around this minimum size.
Definitely something I can look at though. Maybe I can remove some of the stuff that's getting bundled with it and see if it doesn't break anything.
