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.

I like the game, but I choose to not watch an advertisement to respawn and it makes me watch one anyway to go back to the main screen. Even switching which fish I use pops up an advertisement. It forces you to watch advertisements for a longer period of time then you actually get to play the game. It's ridiculous and makes it impossible to have any fun. I will leave it installed for a little while and check later if it's fixed, but if not just going to trash it.
