itch.io

If the APK is failing to work on your phone still. You could always install joiplay from Google play. It allows you to run games like this easily. Just remember it requires a renpy plugin which is also available from Google play (last I checked atleast).

You'll need the pc version (extracted) saved on your phone memory aswell. Bonus is once extracted and tested its working on joiplay you can remove the compressed file.

joiplay needs the exe file for Windows to run. The help files are available online. 

Hope this helps.
