Good concept for a game and fair execution of it but having to lose all your (supposedly synced) progress with what seems like a single crash and have it overwritten by simply landing on the onboarding page is heinous. This is why this game should really support manual saves in Google Play Games as well automatic. Lost all progress despite having GP linked and synced. Contacted support 3 times and have only had automated replies. Spend neither money nor effort on this game.
