Actually addictive idle game

This game. This darn amazing game. I love it. I am a big fan of animals and fish of all verities and this game just has so much fish and its so easy to get money so your not waiting for hours for a penny and the game is so pretty and colorful i love watching the swim and the people just bouncing it really gives me joy to play. I only have been playing this game for a day (and a morning) and i already almost have a finished tank and also there are SO. MANY. UPGRADES. Its so easy to play and its so much fun and very cute and addictive and the trawler is SOOO helpful i get like 20 fish for like 2 ads. So overall its an amazing game and if a player reads this DOWNLOAD IT YOU WON’T REGRET IT. And developers you epic and amazing have an amazing day bye bye.

Dead end?

So, this game is alright. Just alright. It doesn’t quite stack up to other idle games in terms of artwork and completion. I work in an aquarium IRL and was kinda excited to play this game. I willingly gave the $10 for no ads and it completely opened the game up and I was able to complete all upgrades within my first day of playing. I think I have a total play time of 5 hours and have upgraded every single thing. Everything. Now I have nothing to do but watch animations and watch my money collect in hopes that the game gets expanded more. I was a little disappointed that the number of fish you can collect is extremely limited. You only get 4 tanks to show fish in and one of those is a tank to where you can sell fish. The rest of the tanks in your aquarium are predesignated animals that you just upgrade to get multiples of. Beyond that there’s only 30 different fish to collect and you don’t even have enough slots to display them all. The icon of the game even has an orca but nowhere in the game is an orca even used. It almost feels as if this game was only made to push ads in our face. And if you invest in going ad free, well… they got your money so there’s no need shove ads at you.

Mechanically the game is great. There’s only one bug that I encountered after the ship sets sail or comes back to dock that locks the camera in place and makes me restart. But nothing too game breaking.

Not a lot here

There’s not a lot here to keep you long term. It only took 1 week of playing this to “finish” the game. So definitely do NOT buy that “ad remover” option totally not worth it being @ $10 instead of the usual $1 like other games.

Not a lot of of fish to have and they are barely visible when with the ones that you do and place in your tanks. All the gosh are not even that hard to get either, you can get most, if not all, of them in 2-3 days. Also, there’s only 2 kinds of fish for you to find, “small” and “medium.” I was expecting a “large” variant to be involved the more I played through, but no., there’s nothing more. There’s basically only one store for you to manage and upgrade. Once you upgrade everything then that’s it, there’s nothing else for you to do. No other stores to manage and upgrade, no more fish for you to find, nothing at all.

I can say I did did enjoy it, but overall, it’s lacking so much compared to other idle games that it’s just sad when you think of the other more impressive idle games like this one. If they can add more stores or just be able to expand the one you start with more, along with more fish then it could be much better.
