I think you uploaded the wrong thing? There's no .exe file to be found, and the folder is full of .py files.

Hi there. Sorry to hear about your experience with the .exe file. Are you looking in the renpy folder by any chance? There're certainly a lot of .py files in there. I confirm the .exe is in the base folder for SinlessOnMiddleGround-1.0-pc. If you still can't see it, can you please try something for me? Delete the original download, and try a fresh download? If you continue to experience issues, please let me know. Thanks.
