Hey there, this seems like a really cool project, and I looked a bit into the game files and it looks really good! But I couldn't figure out how to run the actual game. I tried doing it using the Itch.io Launcher, and I also tried doing it with pygame. Using Itch.io just gives me this, eventho I put it into the folder, and I even renamed it to bve exactly ".Save file.txt":
FileNotFoundError: [Errno 2] No such file or directory: 'little-runmo-the-game/.Save file.txt'
Hope you could somehow help me with this!
