Google are a nightmare. When I first released Invaders I called it "Space Invaders 2017" and they accepted that, then I got a warning months later saying it was too close to a known game name, so I changed it. Then six months later I get another warning saying I can't mention other games in my description, so you can't have "based on the Space Invaders arcade game".
Policies change all the time, all you can do is keep pushing and make sure you change things quickly when you get a warning, they'll normally react quickly and you can keep it on the store if you do as you're told.
