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.

6-7,相比外传这个说法感觉前传更适合。补充了一下梦美幸福的成长+日常故事,可惜内容太短,仿佛告诉你这美好的一切不会长久。PS:梦美可爱,歌很好听,可惜太短了。感觉可以试试动画。
Good prequel to the real game, very well done
Very short, ~1 hr. of playtime for a nice prequel to planetarian. This would have fit better in the original game as an unlockable side story post-completion.

ohno 好快的结束 听歌来的,小故事白开水
key社精致小短篇,作为前作还行
巨巨巨短,且很差,除了结尾曲还行找不出优点的程度,非常不推荐原价购入,就算和我一样便宜cdk入库也需要考虑一下的质量.........嗯,就很烂,烂到处处漏风你反而不知道从哪儿开始吐槽的烂....和本体相比可以说天上地下级别的差异,也真不知道这一坨官方还敢按情怀作为噱头端上来是咋想的。。。。。。。登场角色不是毫无印象就是出生小孩,谁能不笑?就这么一点剧情,还三次有神人小孩角色???高频到感觉比卖的情怀角色还有存在感一点,不是开玩笑打人熊小孩,就是打机器人还坐在道德高位小路人(顺便,还强调机器人不会痛但是身边人心疼就很。。。??完全不如原作对机器人这个概念的价值观)或者神秘剧情之十年前订婚后面忘了小男孩,雪圈球毕竟只提了一句,你不如改名~熊孩子~。。。然后原作虽然本来我对废土气氛无感,但是BGM搭配演出都很好。。。。这情怀作呢呵呵就真卖个情怀,素材翻新通用一下。。。BGM无聊,故事无聊。。除了强调经营不易就是你那熊孩子,或者动则十年后。。。。本来感兴趣是觉得美少女机器人塑造很成功,有内味也有特色。。。想着最后一段回忆为展开讲讲过去确实不错。。结果就是员工只有女主一个,还是很无聊的角色。。除了说句希望你一直这样,毫无意义,也没有乐趣(相对原作男主开始态度很恶劣到逐渐被打动的过渡...这前传女主真给我一种还不如别藏秘密,直接机器人视角讲新颖还观感更好。)顺便,本身觉得封面还行,但是实际美术也是一坨,甚至可以说没有任!何!和剧情有关的CG。。。。超级食之无味,甚至破坏了原作给人印象留白的程度。。。。。。。呃呃,只能说有这样的所谓情怀作其实很倒霉。。。。我是真觉得你但凡按回忆,写清楚一点日常,或者让员工大家更充实。。。这个噱头细腻一点完全可以和前作整捆绑形成对比两部曲。。。但是现在就是烂完了。。。笑死。。。我觉得四块图一乐都有点不如吃个雪糕,原价购入玩完不退款都是大发慈悲的地步。。。。。嗯顺便,骂的最直接的心情还是美少女角色。。烂完了!照着原作写都不会,非常刻板无聊,除了公式台词一点性格都没捏住的感觉,,,和游戏很烂的美术无聊的叙事毫无记忆的BGM一起化作一坨。。。。有不如没有的游戏
梦美可爱捏
基本就是多年前看过的「星之梦~雪圈球~」,但我依稀记得动画那边还多了几段不错的内容 [spoiler]所以说还有一部「~星之人~」什么时候端上来?[/spoiler]
星之梦的前传,本作流程比较短,2小时内可以通,推荐玩完了星之梦本作的再来玩这部。
画风还不错,挺舒服的,就是太短了,即使我慢慢看,70m也就看完了。似乎因为在定位上是前传,所以故事推进到涉及主题性表达的深入思考时就戛然而止了,提出了一些问题、做了一些分析,但又切出去的很快。还有就是,“雪圈球”感觉和游戏太过游离了一些,好像就没提过几次,大多数时候是以喻体的形式出现在游戏里面。梦美挺可爱的,作为故事最大悬念的擅自离岗最终被揭示为一种玩笑般的可爱原因,最终指向一种朴拙的爱(梦美对他人与星象馆的同事对梦美)。星象馆的员工里美塑造得也不错。不过,还是要说,有的人物没有立绘CG、只有声音,有时候看画面时只有里美,有时候都对是谁在说话恍惚了一下。最后的最后,游戏商店中标注的“轻度暴力元素”实在没看出来,不会是小女孩敲梦美的头吧?
