5 stars: I love this game i find it alot better than clash of clans mostly because everything takes less time to build/upgrade and you only have destroy the headquarters to win. But you can't play this game offline which is definitely a possibility,you could just go o lime when going Into the map or checking someone's basses. Other than that it's a great game.
4 stars: Overall, pretty good, challenging, and time-consuming. Upgrading buildings/weapons takes MUCH longer the higher you go. It's a shame there's an upper limit on all resources. I like figuring out strategy on the seasonal warship challenges that change each season. Only issue with those is that you can destroy the opponent's engine rooms first, but still lose and lose tech points. No idea why.
