AdventureExplorationFishing
$19.99 ~39.1 hr median no co-op complexity: moderate 96.6% of 158k
The Squirrel's verdictSame core loop: dive, catch fish, sell to customers, upgrade gear, repeat. Dave the Diver adds a full restaurant-management layer, a sushi business alongside the diving, and a much longer campaign at 39 hours median. No re-gearing between areas like Scale the Depths, but more systems layered on top of the fishing.
Not for you if you wanted the fishing loop kept minimal, since Dave the Diver stacks a restaurant sim, staff management, and frequent new minigames on top of it.

IncrementalResource ManagementIdler
$4.99 ~4.7 hr median no co-op complexity: light 98.8% of 16k
The Squirrel's verdictShelldiver is a harvest-upgrade-sell incremental where you play as a turtle collecting jellyfish, reinvesting proceeds into a large upgrade tree until the run is complete — all in one continuous playthrough. Reviewers highlight smooth, uninterrupted progression and a 4.7-hour median finish, with every achievement reachable in a single session.
Not for you if you want a multi-session game with substantial length, or you prefer prestige resets as a source of long-term structure.

Cozy CozyLow-stress and wholesome — a game to unwind with.
$2.99 ~47.1 hr median no co-op complexity: light 92.3% of 8k
The Squirrel's verdictBoth loop around collecting aquatic creatures and reinvesting earnings to unlock more. Chillquarium swaps active fishing for passive idle collection: buy card packs, wait for fish to grow, sell for currency, repeat, with no re-gearing between areas. Fits players who liked the collect-and-upgrade cycle but want a background game rather than active play.
Not for you if you want active fishing mechanics rather than watching card-pack RNG and waiting on timers for fish to mature.

CollectathonCreature CollectorIdler
$7.49 ~43.5 hr median no co-op complexity: light 96.1% of 4k
The Squirrel's verdictBoth center on catching aquatic creatures and reinvesting proceeds into upgrades, but Tiny Aquarium replaces Scale's per-area currency reset with persistent progression across tanks, and adds breeding, decorating, and player-to-player trading. Median playtime sits at 43.5 hours, well past where Scale the Depths reviewers hit their wall.
Not for you if you want the fishing itself to stay central rather than becoming decoration, breeding, and tank management over time.

IdlerFishingCreature Collector
Cozy CozyLow-stress and wholesome — a game to unwind with.
$2.99 ~163.9 hr median no co-op 97.2% of 3k
The Squirrel's verdictCornerpond is an idle fishing game designed to sit in a corner of your screen while you do other things: catch fish, level up, unlock new spots, collect currency, repeat. Progress is persistent with no area resets or gear wipes, and at a 163.9-hour median it runs far longer than most games in this space. Suits players who want the fishing-upgrade loop ticking along passively.
Not for you if you want active, hands-on play — the highest-tier fish require manual input, which breaks the idle flow for completionists.

Black Hole Fishing
PCLinux
IncrementalIdlerFishing
$5.99 ~15.4 hr median no co-op complexity: moderate 88.5% of 515
The Squirrel's verdictBlack Hole Fishing wraps a fishing-and-breeding loop around a prestige system: catch fish, breed them, feed mass into a black hole, hit a breakpoint, and reset for meta-progression currency. Fish breeding and idle accumulation distinguish it from straightforward fishing games. Median playtime is 15.4 hours, with the most active work concentrated at the start of each prestige cycle.
Not for you if late-game waiting frustrates you — reviewers flag that mass accumulation near the end involves extended idle periods with little player input.

Cozy CozyLow-stress and wholesome — a game to unwind with.
$6.39 ~17.5 hr median no co-op complexity: light 83.9% of 1k
The Squirrel's verdictAquarist is a single-persistent-aquarium game where you stock, decorate, and maintain tanks to earn money, then reinvest in better fish and equipment — no active fishing, no area resets. It shares the collect-and-reinvest rhythm of Scale the Depths but replaces dives and sell runs with husbandry and interior design across a 17.5-hour median playtime.
Not for you if you want fishing to be the active mechanic, or you need a polished, bug-free tutorial to get started.

Aquaculture Land: Fish Farming Simulation
PC
Farming SimAgricultureEconomy
$9.99 ~7.2 hr median no co-op complexity: light 76.8% of 203
The Squirrel's verdictShares the core loop of fishing, upgrading gear, and selling catches for currency. Aquaculture Land expands scope with plant growing and automation options for players tired of manual grinding, plus a campaign structure. Fits players who liked Scale's fishing-upgrade loop but want automation and a broader simulation, not just fish.
Not for you if you want a tight, well-integrated campaign — reviewers describe the quests as poorly scaled and disconnected from the core loop.
