Opens on 2026-07-14 (JST)
An aquarium where the exhibits have started hunting back, and the friend you came in to find keeps slipping one room further away.
A horror adventure originally released free in February 2024 under the RPG Maker label Gotcha Gotcha Games, then expanded from scratch by its solo creator 橙々 into this fully-voiced Special Edition, published by Frontier Works Inc., a mid-sized company under the Animate Group. Per Steam's own listing, you explore the aquarium's map solving puzzles you cannot proceed without, while misshapen creatures called Creepies threaten to kill you outright. This edition adds full voice acting for its five main heroines, a new "Another Story" scenario, revised UI, added event art and music, and English-language support on top of the free original. Released July 31, 2025, it is Overwhelmingly Positive at 98 percent over 281 reviews (274 positive, 7 negative), a paid title, not free, fully launched and not in Early Access, with no AI-generated assets and, per Steam's own content descriptors, nothing sexual (ids: General Mature Content only). It supports Japanese, English, Simplified and Traditional Chinese, and Korean, and while about 40 of its 281 reviews, some 14.2 percent, are already in English, and Kotaku does carry a page for it, that page turns out to be an auto-generated database listing with no byline or review text once checked directly, not an edited feature — so this remains, for now, a conversation held almost entirely in Japanese.

01First, the one feeling
- Steam's own listing frames the puzzles as mandatory gates you cannot proceed past without solving, and per that same listing misshapen Creepies can kill you outright mid-search, so every room doubles as both a lock you have to pick and a threat you have to read before it reads you.
- This Special Edition adds full voice acting for all five main heroines on top of the free original, so the cast a solo creator once conveyed through text alone now performs the same friendship-and-fear story with full vocal presence, changing how much the missing-friend search lands emotionally scene to scene.
- Clearing the base story unlocks a new "Another Story" scenario exclusive to this edition, so the mystery of who else was really in that aquarium keeps resolving itself after the first ending, rather than closing the moment you find your friend.
02Who this is for (and who it is not)
For you
- You want a puzzle-first horror ADV where every room is a mandatory gate to solve, with real death threats from its monster designs rather than jump-scare padding
- You want a small Japanese solo production carried to Steam: a free February 2024 original by creator 橙々, expanded from scratch into a fully-voiced paid edition and published through the mid-sized Frontier Works Inc.
- You want to catch an Overwhelmingly Positive title (98 percent over 281 reviews) while the West is still mostly absent: only about 14 percent of its reviews are in English, and its lone Kotaku page turns out to be an unedited auto-generated listing rather than a Western review
Not for you
- You want a long game or heavy combat; this is a puzzle-and-exploration horror ADV of moderate length with monster encounters rather than a full combat system
- You want the free original instead; this Special Edition is a paid title, not free and not in Early Access, adding full voice acting, a new Another Story scenario, and English support that the free 2024 version does not have, with no AI-generated assets and, per Steam's own content descriptors, nothing sexual (ids: General Mature Content only)
03The roots of this taste
98% positiveonly 281 reviews — yet almost no one has found it
The Aquarium does not dance Special Edition Buried gem
A horror adventure about a girl searching for her missing best friend inside an aquarium that has turned into a world of terror. Per Steam's own listing, you explore the aquarium's map, solving puzzles you cannot proceed without, while risking death at the hands of misshapen creatures called Creepies. It began life in February 2024 as a free release credited to Gotcha Gotcha Games (the RPG Maker publishing label); this Special Edition, entirely the original creator 橙々's own new work per Steam's own text, adds full voice acting for its five main heroines, a new "Another Story" scenario, revised UI, added event art and music, and English-language support on top of that free original. Published by Frontier Works Inc., a mid-sized company under the Animate Group, it released July 31, 2025 and sits at Overwhelmingly Positive, 98 percent over 281 reviews (274 positive, 7 negative per Steam's own review API). A paid title, not free, fully launched and not in Early Access, with no AI-generated assets and, per Steam's own content descriptors, nothing sexual (ids: General Mature Content only, no sexual-content IDs). It supports Japanese, English, Simplified and Traditional Chinese, and Korean, and while only about 40 of its 281 reviews, some 14.2 percent, are in English, Kotaku does carry a page for it — though checking that page directly shows it is an auto-generated database listing with no byline or review text, not an edited feature, so this remains a conversation held almost entirely in Japanese.
Give it your first passThe Aquarium does not dance (free original, Gotcha Gotcha Games, 2024) The free original
The free original this grew from: released free in February 2024 credited to Gotcha Gotcha Games, the RPG Maker publishing label, by creator 橙々. Per Steam's own listing it already carries the same premise — a girl searching for her missing best friend inside a horror-stricken aquarium, exploring and puzzle-solving while risking death from misshapen Creepies — and sits at Overwhelmingly Positive itself, 96 percent over more than a thousand reviews. The Aquarium does not dance Special Edition on Steam is not a new work borrowing that DNA from outside; it is 橙々's own from-scratch expansion of this same free game, per Steam's own text, keeping the same story and cast while adding full voice acting, a new Another Story scenario, and English support.
