I want to play the game Rift Wizard on my Mac. I have it downloaded on my computer, and know it was made in PyGame. I also know that PyGame things that are .py can be run on my Mac. So, with this in mind, I've been trying to convert the .exe for Rift Wizard into a .py, but I have no idea how. Is there a way to do this? I found a lot of guides online on how to turn PyGame .py files into .exes, but not the other way around.
EDIT: Messing with solutions given by the answers now, but this is NOT a duplicate of the many questions about how to turn a .py into a .exe. This is for the other way around.
