The gameplay of the game is polarizing, with some players enjoying its relaxing and engaging mechanics, while others criticize it for being heavily pay-to-win and repetitive. Many users note that the initial enjoyment fades due to grinding and limited content beyond the first few hours, alongside frustrations with broken mechanics and a lack of meaningful progression. Overall, while the game offers a charming aesthetic and simple controls, it is marred by monetization tactics and a lack of depth in gameplay.
- “Fish Idle 2: Underwater Mystery captivated me with its charming underwater world and addictive gameplay.”
- “The gameplay is super satisfying—catching fish, upgrading your boat, and completing quests feels incredibly rewarding.”
- “Enjoying the laid-back gameplay and fun rewards.”
- “Not to mention the horrible gameplay: 99.99% pay-to-win, abandoned by the developers, rewards are buggy, and it takes years of grinding to 100%.”
- “Repetitive gameplay combined with extremely long level-up time makes it difficult to recommend.”
- “The game's trailer is fake... the gameplay is purely pay-to-win... there are no idle mechanics and 0 offline pay.”

The reviews overwhelmingly describe the grinding aspect of the game as excessively tedious and time-consuming, often requiring hundreds of hours to achieve meaningful progress. Many players express frustration with the game's mechanics, which feel unbalanced and heavily favor a pay-to-win model, making the grind feel even more burdensome. While some players enjoy the grind as part of the experience, the consensus is that it detracts significantly from overall enjoyment, especially for those expecting a more casual or idle gameplay experience.
- “If it wasn't grindy to obtain items, they wouldn't be worth anything on the market.”
- “The grind in this game adds a sense of achievement and makes every item feel earned.”
- “I love how the grinding process encourages exploration and strategy, making each session rewarding.”
- “Grinding never ends.”
- “The gameplay loop is tedious without upgrades.”
- “Currently from what I played, it was awful and extremely grindy at the very start for very little reason.”

The story aspect of the game is centered around engaging quests that involve fishing and crafting, but players report significant frustrations due to numerous bugs and server issues that hinder progress and reward collection. While the gameplay is described as satisfying and relaxing, the frequent errors with daily missions and chest rewards detract from the overall experience, leading to feelings of it being a cash grab rather than a well-structured narrative. Overall, the potential for an enjoyable story is overshadowed by technical problems and restrictive mechanics.
- “The gameplay was simple but engaging, and the story was interesting enough to keep me hooked.”
- “I love how relaxing it is, yet there’s always something to do, whether it’s working on quests or planning your next upgrade.”
- “Relax, catch zillions of fish, cash them in, buy upgrades, do quests to earn chests and items.”
- “The daily quests and rewards are buggy, and you might not get them at all.”
- “While I've enjoyed scooting around in a little boat chasing fish, the fact that the game randomly denies you chests from quests is becoming a significant irritation; those things are useful, and the achievements largely revolve around crafting from what's inside.”
- “Having time gates on unlocks after time gates to do the original quest is a crap mechanic.”

The monetization strategy of the game has been widely criticized as a blatant cash grab, with many users expressing frustration over excessive in-game purchases, intrusive ads, and a slow progression system that encourages spending. Players report that the game feels designed to extract money rather than provide a rewarding experience, with some items priced exorbitantly and a lack of meaningful gameplay without financial investment. Overall, the monetization approach has led to disappointment and accusations of the game being a scam.
- “Shame, it looked fine in the first half (around 24 hours of game time) but the second half (icy land) is just made for microtransactions. I would have refunded it if I could or if I had known about this before getting the game. Shame again.”
- “An idle game that is not free but then has in-game purchases, what the heck.”
- “This game is a cash grab, pure and simple.”
- “100% an empty cash grab with flawed progression and unattainable achievements.”
- “I can't believe I paid money for an idle game that ended up being riddled with microtransactions.”
