Oh wow, that's weird. Usually people who have problems with the game on mobile are expecting an apk file, and unfortunately RPG Maker MV games don't include one. So I'm sending you this devlog in the hopes that it will help you:

Is your problem that you can't unzip the rar file? Maybe you don't have WinRar installed? Could you try using another unzipper maybe?
