EternaMine

Introduction

EternaMine sends you digging through a series of increasingly dangerous mines, fighting monsters for loot and spending accumulated currency on gear, skills and unlocks along the way. Developed solo by Seyloj and released 28 April 2023, it positions itself explicitly as the follow-up to Haste-Miner 2, a popular free browser incremental, and several reviewers arrive already knowing what to expect from that lineage. Three-plus years on, it sits at a lifetime Mostly Positive 79.4% across 97 reviews, with recent English sentiment holding close behind at 78%. This review reads the entire English-language negative sample and a substantial share of the positive one, and finds a well-regarded core loop whose biggest documented flaw sits specifically at the point most idle games consider their second act: the prestige reset.

A loop reviewers genuinely enjoy

The mining-and-combat loop is this review's clearest point of consensus. Reviewers compare it favourably to the digging satisfaction of Minecraft prison servers, and several returning Haste-Miner 2 players describe EternaMine as delivering more of exactly what drew them to the original, with faster pacing and a broader mine variety — standard mines that refill as you dig, deep mines that scale rewards the further down you go, and event-only dark mines that open periodically with tougher monsters and better loot. One reviewer new to the series calls the later content "bullet hell for mining," and points out that "there's so much content, having enough time is your only problem" — a notably different complaint from the genre's usual accusation of running dry.

The prestige problem

Set against that, this review's clearest negative finding is specific and repeated rather than vague genre grumbling. Multiple reviewers across 2023 and into 2024 describe the game's prestige system breaking its own economy on first use. One, writing in February 2024, states plainly: "the economy completely breaks when you achieve your first prestige. One day after I did that I had every upgrade and resources were meaningless." An earlier 2023 review makes a related point about upgrade scaling even before prestige enters the picture, describing costs that "scale so fast that you very quickly hit a 500ft tall 5000ft thick wall." Together these describe a design tension this review can't resolve on the developer's behalf: prestige systems exist to give late-game players a reason to keep engaging, and multiple credible accounts here describe the opposite effect — removing the sense of meaningful choice the moment it's supposed to deepen.

A separate cluster of complaints, concentrated in 2023, describes lost save data — one reviewer reports losing all progress after installing the game on a second device, another describes a save vanishing entirely after a single day of play. This review found no repeat of that specific complaint in the 2024-2025 sample, which suggests it may have been addressed, though it can't confirm that directly.

Still running the lights three years later

What earns EternaMine real credit, and tempers the complaints above, is a form of ongoing support this library doesn't often get to point to for a three-year-old NZ$7.39 solo project: a monthly Contest Mine event, with its own currency and leaderboard, that has run every month without an apparent gap since launch, based on this review's reading of the developer's news feed — including as recently as July 2026. One reviewer in February 2024 reported that particular month's contest was broken and paid no rewards, which this review reports as a real, dated incident rather than dismissing it — but the event's continued operation in the years since suggests it was a fixable bug rather than an abandoned feature. Steam's achievement data shows a healthy, gradually tapering curve consistent with a game that rewards sustained play: the earliest mining milestones clear 55-80% of the tracked population, tapering to the low single digits for the hardest late-game and hardcore-mode achievements — a shape suggesting real, if optional, depth for committed players rather than a wall everyone hits at the same point.

Final Verdict

EternaMine delivers what it promises for a meaningful stretch of play: a satisfying mine-fight- upgrade loop, real content variety across its mine types, and a developer who has kept a monthly live event running for more than three years without visible interruption. What holds the score back is a specific, credible and repeated account of the prestige system undermining its own economy, alongside a scattering of 2023 save-loss reports this review can't fully verify as resolved. Buy it for the loop that exists before you hit that first reset — for many players, per this review's sample, that's already a genuinely worthwhile handful of hours for the price — and treat the prestige layer as a feature still worth checking current reviews on before leaning on it.

Players who want that same loop of digging and gearing up, but expect their reset systems to add depth rather than flatten it, may find Wanderer's own progression a more dependable long-term option.
