Hi. :)The Android version is provided directly as an .apk file, and does not require extracting.
It's possible you may have downloaded the wrong version/file, if it came in a .zip.
Mine came in a zip
Sir I would suggest rename the folder. Just remove the word "zip". It's like a passcode of some sort. I hope it work. Just as the dev said. It's just an apk. And there you have the clue.
It seems PixelDrain was mistakenly downloading the file as .zip on some phones, despite it being uploaded as an .apk.
I have now switched the links to Mega. I've tried with a couple of phones and it seems to be downloading properly now.
Sorry for the inconvenience, enjoy the game! :)
looks like it was only a minor mistake, very well then, have a nice day and thank you
