itch.io

Idk if it works on tablet but try this:

Install  Joiplay and the Ren'py plugin of it.

Link: https://joiplay.net/

Just click the "Download" option and both of them should be there.

After you finish downloading them,  install the game you want to play (Install the Windows version because the others won't work as far as i know.) 

Extract the game file you downloaded and  go to "Joiplay". Click on the plus button which should be on the top right of your screen and click on "add game".  Go  to your downloads and add the game you downloaded by clicking its ".exe" file. 

(Search through the game files if you cant find the .exe file)
