Hi man, I'm an android player and I can say the ping pong game is difficult but not impossible, in my case I play with both hands, I have been practicing and now I can win every match.
Good luck bro.
oh i have to explain it better:
First; Delete the archive Android>Data> Renpy. Then use a cleaner app for trash archives and that things...
When you download the game and it finish, close the notification (DONT CLICK IT). go to your archive's explorer app and install the game.
If you click the "downloaded" notification, the archive crashes (idk why but it happens)
I hope you can install it, let me know when you do it please
