The project is cool and I know the code is not necessarily the point. That said, if I were being picky, I'd ask why the author chose not to use docstrings. The code itself is fine but not very Pythonic. There are small inconsistencies* that running pycodestyle [1] once would have caught and could be fixed quickly — I recommend OP consider that.

*Mostly related to: whitespace / spacing, indentation, mixing single quotes and double quotes, magic numbers, naming conventions
