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): 0.29/day in the week to Sep 1 → 0.71/day in the week after.
Reviews, worldwide (the counter carries no country): 1/day in the week to Jul 21 → 0/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.

作为《星之梦》的前传,《雪圈球》聚焦灾厄降临前天象馆的寻常朝夕。本作取名绝妙,雪圈球亦即雪景球;知晓续作末世终局再品读这段平淡日常,恰似静立窗前凝望雪景球内缓缓飘落的碎雪,温柔安宁,不染尘嚣。天象馆日渐萧条的颓势,叠加既定的末日悲剧底色,更衬得梦美纯粹澄澈的模样格外珍贵,而雪圈球本身,也是梦美最贴切的精神缩影。
真好啊(❁´◡`❁)
这剧情存在与否有意义吗说实话?简直像我小学一时兴起写的作文。史低不推荐原价更不推荐,只是因为情怀就昧着良心打个好评也是没谁了,词里字间看不到半点诚意。

城市毁灭前的梦美“成长”故事。 感触很深的一句话“现在的朴实就是那样,早就已经不是我们那个时代了”
我爱梦美! 地球人,早已在追求着神,并又在创造着神。
这部前传给我感觉怪怪的,没太想清楚想要表达什么,如果可以我会给它一个5/10的分,但是看在前作用两个小时让我在高铁上哭得稀里哗啦的份上给个好评
非常好的前传,重制版画面精美,看完星之梦再看这个还是十分不错
星之梦的前传,挺有意思的,就是太短了
星象馆的前传故事,全语音勉强算85分钟,绝对的粉丝向,感觉体量有些过分,不过特价10港元要什么自行车呢? 三年先看完的本篇,因为这个前传是近些天才在steam首页推荐里冒出来的,时隔三年看到梦美的脸并听到梦美声音就突然鼻子一酸,然后脑子里自动响起《Gentle Jena》,虽说这前传并没有收录《Gentle Jena》就是了,有点遗憾。 这个游戏就是雪圈球OVA动画的视觉小说版,梦美在这时也没什么故障,却也是本篇里那熟悉的梦美,让人有种时光从未改变的感觉,不过通过一些伏笔,也知道了这城市即将崩塌的前兆,然后就衔接着城市瘫痪后的本篇。[spoiler] 之后再是《星之人》里男主的离去。。。 [/spoiler] 抛开伏笔不谈,就是描述了一个简单的小日常,整体基调相当温情,虽说10年工作过去梦美已不再吸引他人眼球,但依然受到身边人的喜爱,看的时候会想,如果没有战争,女主会不会就如誓言所说会一直待在梦美身边,可是未来已是定局,这也只能当作美好的幻想。(依照时间来看,梦美的炫彩缎带好像就戴了几个月,撤离令就下发了,有点小刀。) 略微有点不爽的就是游玩时间了,85分钟体量真的太少,10年的工作就那么一笔带过,我还想看梦美是怎么跟女主关系变好的呢,实在可惜。 遗憾的是个人并不觉的key社会再给星象馆写新剧情,在我看来星象馆相对于该社其他作品来说实在过于冷门,不过也好,梦美由于人设带来的性格特征实在太过强烈,感觉整体形象已经相当饱满了,就让这种“星野梦美”的形象记在心里吧。
比原作还要短的续作,ui/ux已经和其他gal差不多了,和loopers基本一样了已经(因为key社我目前就玩过这几部)。新画风更现代,虽然我还是更喜欢老画风。故事也很简单,写的是原作的前传,在一切还没被废弃的时候,不是原作的那种废土。总而言之还是不错的。
