Did you unzip (with 7zip or any zip software) the folder then clicked on the .exe ? You shouldn't have to use joiplay to play, since it's for windows
I should be able to do an APK for android, where you would have to download it on your mobile phone, but it was not made for mobile play so it might have issues.
After some research it looks like it often happens with ren'py game, I have no definitive fix, but one worked for me, you have to use the latest update with this update of the renpy plugin https://www.patreon.com/posts/joiplay-1-20-032-85460458
It's from the joiplay patreon. It worked on my mobile phone since I develop the game with Ren'py 8.1 it needs one of the most recent update of the ren'py plugin to work, please try this.
