Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Jul 30 → 1/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

- All five heroines are now fully voiced!
- A brand-new scenario titled "The Aquarium will always hunger"
- An updated and brand-new UI design plus event CG
- Full English localization!

Having been gifted a premium pass to Bianca Aquarium, Suze and her best friend, Lulu, receive a guided tour of the place led by the aquarium director’s charming wife, Chrissy. However, when Lulu suddenly goes missing, Suze goes looking for her and inexplicably finds herself in a strange and terrifying world that looks nothing like the aquarium she was at just moments ago.
While searching the aquarium, now overrun with gruesome sea creatures, a mysterious armed woman dressed like a soldier appears before her. The woman, who introduces herself as Retro, is also looking for her companion, a girl named Kitty. Can Suze find her best friend and escape from the nightmarish aquarium before it’s too late? Beware, for a traitor lurks in their midst...

超值 挺有意思的 [spoiler] 你是否在 12 年前救過 ... [/spoiler]
재밌는데 공포 요소를 기대하면 아쉬울 듯
몰입되는 풀더빙 연기력 신선한 소재에 스토리 수미상관과 감동적인 엔딩 작품 분위기에 어울리는 브금 goat 오랜만에 쯔꾸르 감성 한껏 느낄 수 있었다 브금이 너무 좋고 끝에선 나도 모르게 눈물이 나올뻔
살면서 처음으로 해본 쯔꾸루.1인개발이라는게 놀랍다.더빙도 되어 있고(스페셜에디션) 스토리랑 퍼즐들도 괜찮다.퍼즐 난이도는 너무 쉽지도 어렵지도 않아서 적당히 머리쓰는 재미가 있었다.더 널리 알려졌으면 좋겠을 게임.
I heart fish
