Idle DeepMiner

Introduction

Idle DeepMiner puts the player in charge of a single living pickaxe, launched downward through the earth to smash its way toward the core. It bounces off blocks the way a ball bounces off bricks, chaining hits into combos while upgrades, artifacts and a skill tree stack on top of the falling, and the whole thing can be left running in a resizable window while the player does something else. Released 6 July 2026 by the small self-published studio Pantomime Studio, it carries a Positive rating from a genuinely tiny sample — 35 reviews across ten languages, every one of which this review reads. That size is worth stating plainly rather than padding out with percentages that sound more authoritative than they are: this is a small, honest indie release, and the sample reflects exactly that.

A pickaxe that is fun to watch fall

The clearest, most consistent praise across the sample is about the physical feel of the descent itself. Reviewers describe "flashy destruction animations," combo chains that stay satisfying without demanding constant attention, and a pace of upgrades that neither drags nor rushes. One English-language review put it simply: "nice progression, not so slow not to fast." A French reviewer, self-described as experienced with the genre, called the pickaxe's evolution and the balance of resource costs "correct" without hedging further — which, from someone who plays a lot of incremental games, is close to a compliment. None of this is complicated design, but it is well-tuned design, and reviewers repeatedly credit the studio for getting the core sensation right even when they have complaints about everything built on top of it.

Where the content actually ends — and the data that proves it

The single most repeated criticism, in English, German, Japanese, Korean and Russian alike, is length. A German reviewer who otherwise liked the game wrote that it was "actually a great idle game but far too short, a lot of potential" left unrealised. A Russian reviewer complained the game was "specially made to end in 2.6 hours." An English-language review titled its own thumbs-up "Deep mines — shallow gameplay," warning that "the game is essentially finished after about 4 hours," and another reported hitting 100% completion in under three hours for the price of a coffee.

That length complaint is checkable against Steam's own achievement data, and the curve tells a more precise story than "the game is short." The opening achievements sit extremely high — 97.7% for the first upgrade, 91.2% for the first pickaxe milestone — confirming almost everyone who buys this game gets meaningfully into it. The achievement most likely to mark finishing the main content, "The End," sits at 71.9%, itself an unusually strong completion rate for any game. But past that point the curve falls sharply: Completionist sits at 44.2%, and the grindiest achievement in the list, tied to accumulated currency, sits at just 31.9%.

Cross-referencing playtime against sentiment sharpens this further. Across the full 35-review sample, positive reviews have a median playtime of roughly 4.4 hours — almost exactly the length the "too short" complaints describe. The five negative reviews, by contrast, have a median playtime of over 13 hours, with two reviewers logging 14 and 20 hours respectively before leaving a thumbs-down. Read together, the achievement curve and the playtime split tell the same story: the four-hour main run is genuinely well-liked by the people who play it, and the discontent belongs almost entirely to the smaller group who pushed on into the post-completion "endless" mode chasing full clears. One Simplified Chinese review says as much directly, noting the endless mode "isn't as good as what comes before it." There is no prestige, rebirth or new-game-plus system to give that stretch fresh stakes — it is the same loop with higher numbers, and the numbers alone don't carry it.

A fiddly skill tree, and a developer that keeps patching

The other specific, recurring complaint concerns the skill tree's layout rather than its content. A Korean reviewer flagged that upgrade nodes don't collapse or reorganise sensibly, forcing repeated back-and-forth scrolling just to plan a build — a real usability gap in an otherwise low-friction interface. It's a fixable annoyance rather than a structural flaw, and it's the kind of thing a small, attentive studio tends to smooth out over a few updates.

There is good reason to expect exactly that. In the month after launch, Pantomime Studio shipped three separate patches: a bug fix addressing an achievement-sync issue and an artifact upgrade exploit, a fix for a windowed-mode drag glitch, and a small content update that added a new comic scene, sound cues and visual polish for fully-upgraded artifacts. That is a genuinely responsive cadence for a game this size, and it is worth noting given how many idle games in this price range ship once and go quiet.

Value

At NZ$7.39 with no in-app purchases, no battle pass and no DLC, Idle DeepMiner is priced closer to a cup of coffee than a full game, and several reviewers across different languages independently land on the same verdict: fair for what it costs, even while wishing there was more of it. That framing matters. A four-hour idle game at this price isn't undercooked — it's proportionate — and the complaints about length read less like buyer's remorse and more like reviewers who wanted a good thing to keep going. Whether that reads as a compliment or a limitation depends entirely on what kind of idle game a buyer is looking for.

Final Verdict

Idle DeepMiner does one small thing well: a satisfying, well-paced few hours of watching a pickaxe smash downward through the earth, with upgrades that land at a comfortable rhythm and presentation that earns its praise across every language in its small review sample. Where it falls short is everything built to extend that core loop past its natural ending point — an endless mode with nothing new to say, a skill tree that fights the player's own planning, and an achievement curve that shows, in hard numbers, exactly where the goodwill runs out. Buy it for the four hours it was clearly built around, not for what comes after, and it's an easy recommendation at the price. Buy it expecting a long-term idle commitment, and the same data that makes this a fair 6.5 will likely leave you disappointed.
