On it, gonna find the bug! Did you try the demo or the ch.1+2 version?
And if the problem is it's not installing, have you turned on the permission to install apps from unknown sources?

That's very weird, I just downloaded a copy of it from Itch.io and it's working fine.
Let's try one thing or the other:
-If it's an issue with when you open the game and see a grey error message screen, press "ignore" in the bottom! I relocated chapter 1' script location so when the game opens and tries to go back to the place you were on when you exited the app, it can't find chapter 1's script because the demo isn't compatible with the full version!
-And if it can't even install the .APK file, could you try downloading the APK file again? There's a small chance it could have corrupted in the download.
