Perhaps I can help you out?
Unzip (unpack) the file.
After unzipping, go to the directory you just unzipped it to.
Find the renpy icon, and click on it.
That's odd.
Just for the record, the game was originally named "broken" and I never switched out the apk, so it's still showing the old title.
It doesn't mean that the game is broken.
It's actually showing up like it should.
You're not seeing a file called renpy? If you are, click on it.
If you're not, what kind of Cell phone are you on? As it's a cell phone, I'm going to guess it's updated and not playing some pre-historic version of Android.
