Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
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 Aug 31 → 0.86/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.

This game is a buggy mess.
Lots of ♥♥♥♥♥♥♥ bug, first 10 second into the game im stuck in a rock, then i slept on the bed and my chracter slide across the floor, there is more but ion wanna waste time
真不想给差评,可你们的问题也太多了吧! 首先是bug部分 : 像是什么墙里长草、人物卡墙里、音响会自己切歌、隐形墙、射线镐激光消失等等…这些我都算了 特别是那捡物品,打怪的音效,也太声了吧,还不做消音;比如把箱子拆掉时时,里面的东西都会爆出来,这时如果过去捡的话,由于东西非常多,就会被叠的超级大声,打怪也一样,同时打多个怪时声音就会叠的非常大声 其次就是自动化: 这个传送带真就一点也不好用,不如把传送带全拆了让魔物娘搬,还有那个无人机,明明里面满了它还要往里面运,导致一直掉出来,也没个设置什么的,比如少于多少往里面运,高于多少停止 说到无人机就不得不说一下以前的版本,以前的版本里无人机是可以跨层数运输的! 以及还有一种设备是可以在特定范围内运物品的,具体表现为放下来后会出很多的扫地机器人,可以对范围内的所有设备补充所需要的材料,并将做好的材料运出! 也不知道怎么想的,在正式版中又把这个删除了,就想让玩家玩那传送带是吧 然后是魔物娘部分: 给不知道的人说一下,箱子是可以设置分类,禁止魔物娘使用的,这样可以有效仿止魔物娘乱放的情况 首先是工作适应性,连个优先级都没有,钓鱼的一天到晚只会钓鱼,种菜的一天到晚只会种菜,还有做饭…这游戏的物品一组居然是9999?!都做了几千道菜了,还搁那做菜呢? 然后就是种地,你都能禁止魔物娘使用箱子了,为什么就不能禁止魔物娘使用田地呢?我装饰用的花,给我收了又种上新的,我用围栏围起来,结果就是闪现进来收掉,完了又种上新的闪现出去,给我气笑了 还有那寻路,为什么种菜就不是就近种的,而一排一排种,她需要从左往右一路种过去,然后走回最左边,再从最左边种到最右边 就像这样 →→→→→→→→→→→→→→ →→→→→→→→→→→→→→ 而不是这样 →→→→→→→→→→→→→→ ←←←←←←←←←←←←←← →→→→→→→→→→→→→→ 如果你的田地很“长”的话就会像这样来回走路,原来效率慢的原因在这 至于那战斗,几乎没啥用,还特别费药,升星又只加战斗数值,即然你都缝了,就不能加点工作效率、搬运速度什么的吗 剧情也是一言难尽,就像那种有点写不下去,乱写凑字数的感觉 作为一个从首发到正式的玩家,见过这个游戏一点点下滑,越做越倒退回去,从一开始的特别好评到褒贬不一 为了出个创意工坊还把玩家存档全删了(受害者之一),结果创意工坊里没有几个模组,那个几个皮肤mod都是自己人发的 总体的来看,目前不是很推荐!

全実績済み 軽め~ほどほどに採掘・自動化・工業系がしたい人にはおすすめ 戦闘とストーリーはおまけ 魔物娘(戦闘 or 作業をしてくれる)不要な人は別ゲーで良い ・下記があるので正直未完成なゲーム ちょいちょい不親切 クラフトや図鑑に検索機能がない バグそこそこ有り 動けなくなったり壁抜け亜空間等のバグも発生したが、拠点に戻るアイテムで解決できるので詰みは未確認 レシピがあるのにクラフトできないアイテムがある(壁掛けランプ系) 無くても致命的ではないが、使いたかった つけっぱにするとめちゃくちゃ重くなる タイトルに戻れば解消 同じく重くなる人とならない人がいるらしいので環境による? ・実績について 作業実績用に古いガイドを見ていたところ、取り返しのつかない実績(取り逃しても別ワールドで取れるはず)が今より多かったようだが、現在は下記3つ [spoiler]・一刻を争う:50日以内に地心の町に到達する 4層に50日以内に到達。横道しすぎなければ大丈夫と思う ・殉教者:ノーマルエンディングを達成する ・新世界:パーフェクトエンディングを達成する[/spoiler] 分岐条件:[spoiler]8層の左下の部屋のコンソールを操作 1ワールドで両方達成したい場合 コンソール操作前にセーブ→どちらかのEDでクリア→タイトル→ゲーム開始→ワールドの右にあるロールバック→クリア前のセーブをロードしてもう片方のEDクリア[/spoiler]
不知道什么时候买的了,无法退款。一个卡通风格的游戏开屏就是一个女生的ru摇,我就知道这个游戏的受众肯定不是我
ну чтож, игры может быть похожа на core keeper(подземелье), necesse(нипы делают в лагере работу), terraria(как популяризатор таких игр в 2д жанре) и stardew valley(отношения нипов, посадки, квесты). в принципе ничего нового. Кому то захочется взять из за из-за плюсов выше перечисленных игр, но сама игра показалась более казуальна, чем все они. Могу сделать вывод что ее берут из-за фан сервиса - фурри, суккубы (дальше не знаю) которые могут принимать душ) и купаться в басике))). Это конечно все прикольно, но но больше у игры ничего нет. Геймплей - попал в локацию, тебя херачат - добыл ресы - сделал шмот - ты херачишь. Прокачка - по изучал местность, собрал ресы, прокачал перса\нипов. + шмот на тебе\нипах. Отдельно по визуалу - дебильные эмоции перса при разговорах. ну тупо фансервис для подростков. игра приятная, но не оч красивая. да и ощущается как флеш игра. Интерфейс - поддержка широкого экрана хреновая. менюшки выползают за пределы. но оставляют где то пикселей 10 что бы выбрать персонажа для тех или иных действий. играбильно но с огрехами. + мало настроек, зачем мне интерфейс на весь экран? хотелось бы иметь возможность настроить размер. Лангуаге - инглишь в принципе простой иногда). на русском лучше вообще не играть, если выхода нет то можно, но будешь гэкать с разговоров персов) Геймпада отпадает - жуть. перс смотрит на курсор, (когда двигаешься с помощью. стика, курсор в ту сторону и показывает, да он не пропадает), менюшка выбирается только с помощью стика. Для меня 4 из 10, но если человек новичок и не играл в похожие жанры - то для него будет 7-8 из 10.
Surprising little find, I just hope they make more! <3
Yep its great, i would love it if the first boss didnt drop a broken pickaxe with 97% power though destroys the whole progression on layer 2-3-4-5-6 and so on. Why drop something that good that early? just remove it from the drop pool or nerf it to have the same power as layer 1-2 pickaxe MAX. It killed my dopamine i was having lots of fun untill then kinda forcing myself to play now to get to later stages where new upgrades matter again but it seems thats even higher then tier 5? idk. Steady increase in power is the way. Short but high dopamine rewards just ruin it. To developer: please add a quickstack items to nearby chests! like 10 block range or similiar having to sort items all the time is a pain, would be a huge quality of life update to the game. also the pickaxe thing. otherwise so far early game is 10/10
神秘小游戏,其实我是不推荐的,但是买都买了就当支持国产了。
Core Keeper clone, but you have female slaves
