Great 2D layout in battles and 3D for ships which could be configured (ship colours etc.) Too many ads on different locations. I purchased the app and there are still ads if 'Rewarded video' is checked in Options (default). Some ads could be inappropriate for kids. I would prefer to be password enabled for all 'Options' and not only for chats. 'Playing with friends' option preferred. Could be hacked but devs have worked on this. To be recommended, but not yet (until password in Options enabled).
