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): 2.29/day in the week to Sep 10 → 5/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.

気をつけろ…このゲームは危険だ ただ解くだけなら鼻くそをほじりながらでも出来る その先だ…解いた後に頭をよぎる それは「完成」なのか？ あぁ…分かっていた 分かっていたんだ、そんな考えは無視すればいいと でも、このゲームは解いた後に３つのグラフと言う地獄へのチケットを見せてくるんだ その３つのグラフ全てを「最高」にする事は不可能なのは分かっている 分かっている！ でも、効率厨は効率を目指すんだ 完璧主義者は完璧を目指すんだ 承認欲求の塊は誰よりも最高を目指すんだ 負けず嫌いは「その他」に埋もれたくないんだ 気をつけろ このゲームは解くのではない 「解く」その先「完成」を目指すゲームなんだ 気をつけろ 囁いてくるぞ 「それで良いのか？」と 気をつけろ 囁く悪魔は他でもない 自分自身なのだから 気をつけろ 見惚れるくらい完璧に作っても 後日、再び見た時それは「不完全」なものに見える 聞こえるから 悪魔の囁く声が 「それで良いのか？」と…
If you like Factorio, shapez, or Satisfactory, you'll get a kick out of this. You COULD brute-force every solution, but it is so satisfying to make your solutions as efficient as possible.

The game's main drawback is the lack of a performance graph (any cycle/gold metric) of other alchemists. Cost and Cycle graphs are useless because creating the cheapest or fastest mechanism is easy. The challenge is combining these two parameters. This would add some kind of competition to the game. Otherwise a very good game.
This game has a solid foundation, the core mechanic is easy but it has the perfect learning curve. Im halfway through the campaign and I am having a blast.
Even though my brain can't comprehend the puzzles in this game, it's fun to slave over them for hours just for the solution to be so bad you slave over them for another hour. Great game

I'm having a blast. The puzzles are interesting, and the difficulty really scales with the player instead of the game. If you just want to make the output, I'd say it's easy-medium difficulty. If you try to optimize your design for one metric, it's medium-hard. Trying to optimize machines for all three metrics + elegance takes it up to hard-impossible / can always be better. The game does get more complex as you progress which is nice. Seeing how your designs stack up to other players / people on your friends list is very motivating. I haven't finished everything yet, but I can confidently say this is a great puzzle game for any skill level.
After playing games with a lot of qol content, this game feels poor. Good idea, but where is my symmetry? My copy paste? My saved subsystems? Too painful and long to make machine. As someone that loves programming, I cannot recommand this game. I will persevere a little bit more to see if I change my mind.
Sigmar's garden is a great game and you even get an extra dlc attached called opus magnum. Very worth
Alchemical game about being an alchemist and feeling like a genius every time you optimize your work. It actually also has a very solid story and good music. Starts chill but get very hard/rewarding towards the end.
