Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 1.57/day in the week to Aug 23 → 2.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

mi ha cambiato la vita...
Collect fish, make money, have fun
I tried so hard do like this game. After playing the demo I was like "meh" and forgot about it. Then it was part of a bundle and I installed it again. Turned it on multiple times over the past weeks just to realize my first meh should have been enough. - The UI is very bad. You have a huge box that shows four fish at a time and I even had their long names make them reach over the edge of the screen. This way I was not able to click the lock button on their right side anymore. At least let us change the size of the grid and fishes shown at once! - You need to manually check all your fishes over and over again and lock every fish by hand to make sure you are not selling something you don't want to. There is no search bar, you can only sort your fishes after some criteria like rarity and age. No obvious "auto sell adult fish below certain rarity" option. - Your aquariums will stay barren for a long time. You can't decorate them, because that would be way too expensive and you need the money to unlock higher value fishes. - No info about the fish, just their names. - The only mechanic in the game you can use to progress faster is to feed them. For that, you have to position your mouse on the screen with a right click and let the fish munch on the food you drop. It's boring af. On top of that, all the adult fish will eat food as well - so they take away xp from baby fish and the whole grow up process takes even longer. - Progression is extremely slow. After 16 hours I unlocked the third aquarium and I can't even populate it with saltwater fish, because only one batch of them costs more than my daily passive income. You would have space for 60 fish and it takes me more than a day to put just 4 inside the tank. - The grind starts from day 1 and doesn't get better. It starts slow and stays slow. You really need patience to continue playing this game. - Drop rates for the rarest fish are extremely low. After all these hours, I didn't drop a single rainbow coloured fish and only six golden fish in total. You don't have enough space to justify these low drop rates. - You can't turn the music off when game is not in focus. So I really liked the art of the fishes and collecting them at first, but the super boring and slow grind is simply not worth my time as you can't even run the game properly in the background.

Great game nothing to say
Played it with an auto-clicker and made it a pretty nice active-idle and collector game. Fun to learn a lot of new species or collect your favorites.
Très décevant, pas chill du tout. Certes il y a une méthode pour que le bouton reste enfoncé pour nourrir, mais si on quitte le jeu ou la fenêtre ça ne marche plus. La vente de poissons n'est absolument pas optimisé, c'est un vrai bazar. Certes on peut filtrer, mais c'est clairement insuffisant. Il faudrait pouvoir revendre automatiquement les doublons adultes. Aucune amélioration d'alimentation automatique, alors que le niveau d'xp demandé par les poissons est gigantesque. Le jeu manque clairement d'optimisation et aucun mod pour cela.
