Hello. It looks like you haven't uploaded the complete set of files. In order words, you need to upload the ZIP file created by Ren'Py when you build a distribution

Hello

Forgive my ignorance, but when i finished the Demo, i just went to Ren'py, clicked "Build Distributions", Chose the available versions possible (Windows, Mac, etc.) and converted it. I didn't do anything before this. Even though i put a couple of links of other versions of the game that can perfectly work (they are in google drive sharing links), once they carry all the files a game folder has.

If you wanna tell me a suggestion or anything on how to solve this problem, i would appreciate it.
