Prices
The United States storefront in every case, so this compares stores and not countries.
Prices
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): 56.83/day in the week to Jul 17 → 3.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

At the beginning, I was lost and couldn't understand how to play the game. I had to try a bunch of things for almost ten minutes and to start a new game before understanding what I was meant to do. Even after this, I just felt always lost, like I was completely in the dark and honestly, I did not like this. I don't think this game is made for me because I needed more instructions, or at least clues to better understand the game. As I couldn't progress a lot in the game, I have not a lot to say about it but I still find the graphics really beautiful. Edit : I tried to play it one more time and, this time, unlocked a few rooms. I'm still very much confused about what to do, so I'm now sure that this system of playing is not for me. It also bugs me, when I read some reviews, that people needed to heavily use the wiki to progress in the game. Still, I was less frustated about it, which allowed me to enjoy the graphics and the little music. So I think I would recommend this game for someone who enjoys mysterious, cryptic kind of games, but I will pass on this one.

被主页耽误的好游戏,比想象中好玩很多,很爽的一款模拟经营(?)游戏
每当我想读书或者升级魂质的时候总是强制转到制作物品,什么时候才把这个bug修一下? I just want to read books. Sometimes when I want to read, it ends up being about crafting. Whenever I want to read or upgrade my soul quality, I'm always forced to switch to crafting items. When will this bug be fixed?
Too-real can't find anything in my catastrophically cluttered house simulator
One of my favorites. Just a fun, relaxing, but slightly brainy puzzle. And I love the esoteric theme.
당신이 창고를 항상 다 채우는 햄스터 파라면 그냥 사세요.
初期の行き詰まりを突破するだけで4時間ほどかかりました。何をやっていいか分からず、図書館にすら入れない状況が続きました。最終的にYoutubeのプレイ動画を参考にしてようやく理解し図書館に到着。 その上でさらに、全体の進め方やだいたいの流れを掴むのに2時間ほど。 しかも理解しても難しい。特に難しさの原因になっているのは、 ・コスト(INPUT)と獲得(OUTPUT)が明示されないため、必要なリソースを獲得するために何度何度も手探りで繰り返すしかないこと。 ・おまけにシンボルの種類も多すぎて訳が分からない。普通はせいぜい5~6要素では? ・コストと報酬の関係が明示されない上、法則性を見抜こうにもシンボル多すぎて把握しきれない、という最悪のコンビネーション。 普通の人の把握力と計算能力と根気の限界を超えているゲームだと感じました。 もしかしたら前作のCultis Simulatorをプレイ済みの人向けなのかな?とも思います。そちらはプレイしたことないので分からないですが、この作品よりかはまだシンプルらしいです。
플레이버 텍스트 읽는 거 좋아하는 취향이면 강력추천함. 컬티스트 시뮬레이터는 좀 해보고 오는 게 세계관 이해에 도움이 될것.
그... 재밌어요. 이 게임 하다가 n년 방치했던 노션을 다시 씁니다...
