So addicting and great for when you’re bored

When I saw this app I saw it on the ad and I didn’t buy at the first few times but I thought why don’t I give it a try and I’ve been playing this game nonstop it’s super fun and you can collect different fish which is super cool I haven’t gotten all the collections but the best one so far for me is the rubber chicken if you ask me this is super good for if you’re bored or have no Internet I was just playing this game now and I can say I’ve never seen a game like this so attached what’s the cutest one so far to me is the corgi I love this app this is super fun and the I love that you can play with other people that are online on the game and you can get power ups it’s just a really fun game and I love it

Names and ai

So uh ok hi I know this is probably not gonna be seen but I’m gonna write a review. So to start the game is fun and enjoyable I was actually playing it before I was writing this. But there is some problems to start I would like to suggest the idea of ai and players ai being a filler for the slots that aren’t, real players. But speaking of players let’s talk about there names. Now here is the part in the reading where you incinerate my review for the public to never see because I know this could get rid of half your young player base but names not only have I found a name that I can’t even say it has something to do with the word donkey but for all you kid or adults reading this if you can I found even more question mark. Because there are some foreign languages but I don’t know them so I can’t read them. But that is my review it’s a good game but take my word and implement them into not only your game but your game page if you don’t know what I’m saying change the age rating but that is my review

Review For Fish Go!

I really love this game because you can be a shark and battle a lot of people and buy any fish you actually want. This is way to fun to play and I cannot stop playing it everyday, and getting daily rewards is so awesome! You give us free stuff for battling and I like it alot but the ads nahhhh I don’t wanted them but they need it for money so please keep the adds! I have been playing this for 2 hours already and not getting off and when my IPad has no percent and has one percent I think of the game and click on it and that’s how special it is to me to play! Please make more updates and rewards please so you can make the game more enjoyable.
