Fantasy Idle Dungeon

Introduction

Fantasy Idle Dungeon asks the player to hatch, raise and fuse a roster of creatures called Jenin, gear them up through enchanting and socketing, and send them off to auto-battle through an infinity tower, sealed ruins and other themed realms — checking in occasionally to reorganise formations or push into harder content. Developed by Leaves Games and published by Gamersky Games, it released 3 December 2025 following a public demo period stretching back to August 2025, and sits at Mixed, 69% positive, across 732 reviews. It's worth noting upfront how often this game's own reviewers, on both sides of the recommend button, reach for the same comparison: Dragon Cliff, an established idle creature-collector, comes up repeatedly and independently, both as praise ("Dragon Cliff with cute Jenins!") and as a pointed criticism ("Save your money and get Dragon Cliff instead"). That's a fair frame for this review to work from — Fantasy Idle Dungeon is playing in a genre with an existing high bar, and its own audience is measuring it against that bar directly.

A real, if familiar, collection loop

The core appeal here is genuine rather than borrowed goodwill. Reviewers describe real satisfaction in building out a Jenin roster, experimenting with formations, and watching gear progressively upgrade from common to legendary tiers — one 838-hour review calls it flatly "10/10... the mechanics all make sense and are very fun," and a separate hundred-hour-plus review argues that players calling the game merely grindy "must never have played an idler before." The creature designs themselves draw consistent, specific praise for variety and charm, including from reviewers otherwise unhappy with the game.

The localization problem is the real story

Set against that is this game's single most consistent complaint, and it's a specific, checkable one rather than a matter of taste: significant parts of Fantasy Idle Dungeon remain poorly translated or entirely untranslated well past launch. "There is a lot of it that remains untranslated, so I cannot understand some things," reads one 135-hour review. Another, at 137 hours, is more pointed: "There is a lot of missing English translations... no direction on game progression." A third catalogues the problem precisely — "translation doesn't make sense for some stats; for the same stat, tooltip elsewhere is translated differently; some tooltips are just English words jumbled" — and a fourth, as recently as July 2026, still lists "missing translation" among current complaints, alongside a note that set-effect text remains displayed in Japanese. Multiple reviewers separately report that the in-game help button routes players to an external support site that is itself untranslated. For a game selling on the English storefront, this is a genre-independent, structural problem, and its persistence across roughly eight months of reviews suggests it hasn't been meaningfully addressed rather than being a one-time launch rough edge.

Pacing built around patience, not always successfully

A second, related complaint concerns pacing. Several reviewers independently describe the game as tuned around leaving it running for a full day rather than checking in periodically — one notes it "shouldn't be faster to grind gold" through active play than through simply idling, and another reports the most efficient strategy is parking on the very first, easiest stage rather than progressing, since it clears faster than harder content pays out. A related complaint concerns an in-game currency-earning mechanic that one reviewer describes as originally functional before being "nerfed so hard it's not worth trying anymore." None of this is unique to this game within the genre — idle games routinely ask for patience — but the specific complaint here is that active engagement is actively punished relative to passive waiting, which several reviewers read as backwards incentive design rather than a deliberate feature.

Bugs worth flagging, and a support record worth crediting

A quest-blocking bug preventing progression past the game's opening is reported by multiple reviewers spanning from launch week through July 2026, and a separate cluster reports memory-leak symptoms — one reviewer specifically connects unusually high RAM usage to an unexpected PC reboot that cost a 48-hour save. One July 2026 review claims the developer has abandoned the project, citing an inactive Discord. That claim doesn't hold up against the game's own public update record: Fantasy Idle Dungeon's Steam news feed shows a new update as recently as 1 August 2026, twelve days before this review, following a steady cadence of content drops through the preceding eight months — a genuinely active support record this review can confirm directly, even if it hasn't yet resolved the specific translation and stability complaints raised above.

Value and monetisation

At NZ$14.75, Fantasy Idle Dungeon carries no in-app purchases beyond a single optional supporter pack explicitly framed as a way to support the developer rather than a gameplay unlock. That's a clean record, and several reviewers who bought the supporter pack say so explicitly while still raising their other complaints — a useful signal that the criticism here isn't rooted in monetisation frustration.

Final Verdict

Fantasy Idle Dungeon has a real, satisfying creature-collection core that a genuine slice of its audience has sunk hundreds of hours into, and a developer that's kept updating it well past launch. What holds the score down is concrete and specific rather than vague dissatisfaction: extensive localization gaps still present eight months after release, a pacing design several reviewers argue punishes active play, and a recurring quest-blocking bug alongside independently reported memory-leak symptoms. Buyers who've enjoyed Dragon Cliff and can tolerate patchy English text while the developer keeps working may find real depth here. Anyone who needs a fully polished, fully localized release on day one should wait and watch whether the translation work catches up to the content.
