2 hours to get all nodes in the skill tree, 3 hours for 100% achievements Skill tree is very linear and random No interesting unlocks Unlocking new fish can decrease income due to their increased HP but low yield Nothing is explained, it can be a kind of style when it works but doesn't work in this game

Deep Sea Fish: Hidden World is an enjoyable enough game for the first couple of hours that becomes more and more tedious as it goes on. Positives: - Attempts to make the game less grindy. I usually managed to afford an upgrade after every run. - The game's graphics are quite nice. - Upgrade tree is easy to understand. Mixed: - As the game progresses the fish gain more health than you gain fishing power, this makes collecting some fish more difficult and boring. Some may like this added challenge. - Could argue they overuse the abilities and you need to rely on those to catch the larger fish. Negatives: - Dull soundtrack with little variety. - Achievements are not all completed when I finished the game. The go fishing 200 times achievement also seemed to be broken on my game. - Levelling to 150 seems to make no gameplay changes. - Levelling in the game is boring and just slows down the fishing. An auto pick option would fix this. - Lack of map variety. - Larger fish are far too difficult to catch in terms of how long it takes to catch them. 5/10: A boring game that looks nice and plays ok. Not for me, some may enjoy.

Very smooth and chill game, except for that thing that happens every 30 levels. Thalassophobia warning.

Fun game. Only thing i wish that it would be nice to see how many u caught together, not show only cash and also it would had be nice to understand % vaule, it was confusing to understand what fish book % means and i though 1st it was cash amount and would be nice to see fish hp also. But super fun game and only small confusing parts.

Games like Noita for the two things it really does: spells you assemble yourself, and a simulated world that takes nobody's side. Seven picks, from a slugcat to a dwarf fortress.

The Tormented Souls price has not budged in six weeks of our readings. What that means for buying it, and whether the 2025 sequel is the better purchase instead.
