Prices
The United States storefront in every case, so this compares stores and not countries.
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/day in the week to Aug 17 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

游戏就像操逼, 光好看是不行的, 你得好玩。 你他妈不好玩有个屁用啊。 给个好评鼓励一下啦
简单的操作方式,通俗的故事,美丽的价格(免费最合适),惊艳的画风。 [h1](特别对于全成就党)[/h1]一大堆缺点: ①单一的音乐久之让人烦躁。 ②休闲的的游戏让人一直找东西,让人很累,哪怕在这个简单的水下世界。 ③休闲性-挑战性平衡的缺失 ④成就24h↑
相当不错的禅类游戏,清新靓丽的画面与BGM融合后会给人一种治愈的感觉,操作也简单(单手即可)。本来以为是个类似小蝌蚪找妈妈的游戏,玩了后才发现游戏也有条自己的主线故事,全收集+配合右下角隐藏的短片动画后能猜出个大概([spoiler] 总体还是保护地球环境[/spoiler]),比较推荐空闲的时候游玩,顺便给自己来场简单的净化与治愈之旅~!

(之前评价写在已经挂掉的萤火圈app了,现在看到了顺便根据回忆补个档)乍一看画风不错,小清新的国产游戏,收集要素特别烂,部分关卡的被电击音效特别突兀刺耳,故事线也特别不清楚(全藏在本身就不好找的收集要素里),玩完特别痛苦
Simple and relaxing zen exploration sim. Very simple and tranquil.

16年在手机上玩过。当时正在准备考研,还有两个月时间,放弃了耗时相对较长的DOTA,非常有幸看到了这款小游戏,在复习放松的同时,不费时间,同时游戏中的小鲤鱼又充满了向上的精神,给了我鼓励。现在研究生毕业多年,看到这款游戏steam有售,果断支持一下。感谢制作团队,非常棒!!!
挺休闲治愈的
I'd definitely recommend this game its very nice looking and also has really good sound design. There's little plot but it works well. My only real complaint is the last 2 levels are very large and confusing and seem a little rushed. Besides the last two levels its a decent game especially for the price.
