I would give this a higher rating as it's not a bad game to play but you literally have to watch an ad for every function of the game. Want to look at the different levels of fish you must unlock, ad. Want Way to play the game, ad. Finish the round, ad. And the minute long ads is just too much. Way, way, way, way too many ads just to try and play the game. Get rid of the ads and I'll change my rating.

it's fun but it's annoying, especially on single player, because they will just start Spawning in levels that are WAY higher than you, and if you're even one level lower than whatever you're fighting, 90% of the time you are going to lose, because one level higher is vastly stronger than you. Also they hit you with an ad after so you can't watch one to respawn.

after 34 hours ..... I can say I want to like the game but. the leveling is off balance between AI and the real player. it seems once you hit level 50 every fish attacks you. the clam power ups could use a buff or more time sometimes you dont find any other fish. leveling a fish to level 39 takes for ever! the coin buffs need to be buffed its like you put in all this work and get a .5% buff( basically nothing) id like to see at least 1.5% for each coin 3% would be even better!!!!
