I downloaded the apk from mega, installed it on a virtual smartphone - it works, no emergency messages. I don't know how to deal with this. Maybe the game's author will help. Your idea about simply copying files is basically correct (the game itself is an interpreter, it doesn't care what to display on the screen), but once, when I did this (on Windows), the game crashed when choosing a blonde hair color.
On a virtual smartphone, it looks like this:
вот обновленный вариант, вроде бы должен запуститься:

Well, it's not hard to delete the game. It's more difficult with saves. This issue has already been discussed here in the comments, but I don't think there's a universal solution. The only thing left to do is play through it again, I guess. I've already done this involuntary several times while testing the translation.
In Windows, saves are recorded separately from the game, but as for Android, to be honest, I don’t know.
I have a Russified version of 68.1, but I haven't converted it for Android. I think that if I do, it's unlikely to work. There's some compatibility issue here, probably. I'll try to install another emulator that has an environment for smartphones Xiaomi with your variant OS. It will take some time.
But it would be best if the author packed the files with the translation into his own APK file.
