If you like the ocean and the idea of merging, like me, then you should get this game. After all it is a great time waster. There are 3 problems; first there isn't different maps to play in. There should be different maps that have different areas. 2nd, there should be like a code system that you can type it in to join your friends. On top of that when you finish a survival, it says, you've worked hard, take an ad break.then an ad comes. Remove that feature.but it is great and you should try it.

The concept and gameplay was cool. There is also an ad after every round, and it's a non-skippable video that's often around 30 seconds, maybe more. The other "players" are all bots; there is no multiplayer aspect. The game was too easy at first, but it kept progressively getting difficult to the point where it felt like winning was a game of odds rather than skill.

This game was absolutely fun to play, Especially if you have nothing to do. You can Get new backgrounds, Fish Skins, Play Mini Games, and Basically you merge your fishes to get new fishes. Before I had to uninstall it due to my storage, I realized two things that were a bit annoying when I first started. Because first, Every round, you would get an ad. No matter if you win or loose. And second, I re-installed it, but I was back to level 0. Overall, I'll give this a 4/5.I hope you can fix this<3!
