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 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.

Histogram go brrrrrrrrrrrr
I should be working on my own game instead of playing this one but here we are. 10/10 would be unproductive with this gem of a puzzle game again. Mesmerizing and satisfying when you come up with an elegant solution.
First we opus then we magnum, lets opus magnum

A great game that really makes you think. A simple plot, but amazing puzzles set to a beautiful, relaxing soundtrack.
I absolutely love this game, it's brilliant, don't be put off by the fact that the instructions seem complicated, you can finish the main campaign without having to do anything ridiculous, but once you have done that if you are anything like me you feel far from done, and will now want to go back and re-solve them all in new / more efficient / just different ways, as well as the fact you also unlock some additional puzzles that are quite a lot tougher, and there is some bonus content and a DLC, I'm working through the DLC at the moment but as you'd expect it's more advanced than the main game and I'm taking my time with it, so I haven't finished that yet, it seems well worth the money so far though
This game is fantastic. The gameplay is really engaging and the balance between teaching you how to play and letting you figure things out for yourself is perfect. One of the great features that really keeps the game interesting is the three different metrics for a solution, with separate leaderboards for each metric, which encourages you to explore multiple different approaches for each puzzle. If that doesn't interest you, you can turn the leaderboards off and just play the game how you want to play it. The puzzles get progressively harder, so you go from simple puzzles where golfing for the optimal solution is easy, to real challenges, where getting a solution that works is tricky enough, nevermind a solution that's elegant and/or optimised. Even when you finish the game, there's a wealth of challenge levels available to play, and community levels in the workshop to download. Not to mention, the creative direction of the game is gorgeous; the artstyle is lovely and the music really fits the theme. The storyline is interesting and engaging, and I love the theme of a prodigal student alchemist graduating and entering the world. If you like sandbox puzzle games, spatial puzzles, programming challenges, or automation games like Factorio, this game is for you. I cannot recommend it enough.
I’m in a love-hate relationship with this game. Gameplay: I love puzzle games and enjoy brainstorming. But sometimes, one mistake makes my whole build fall apart—so it’s delete… delete… delete. Big sigh. However, when I finally manage to finish it, I often come up with another way to make it even more efficient. Then again, you can’t make something efficient without either spending more resources or using less but taking up more space. I really love that aspect of the game because it adds more challenge and pushes you to create new ways to solve problems. I’m playing this competitively with two of my friends. We have different personalities, so the way we approach problems is entirely different, which is very interesting. The mini-game is also hella fun. Graphics & Sound: They fit well with the game’s style. Frustrating Parts: The chapters I can’t finish or escape from are haunting my dreams.
Addictive puzzles.
Yes.
Feels like Factorio meets Scratch. Super satisfying if you're into sum autist ♥♥♥♥. Love it.
