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.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
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.

機械構造をひたすら追求するのが好きな人はきっとハマる。 ただしカジュアルゲーマーで目に見えるご褒美の欲しいタイプである自分にはNot for meでした。 ひたすら数式を眺めているような感じで、ちょっとビジュアル的に地味すぎました。 せっかく錬金術で魔法的な変性をしているのだから、もっと視覚的に分かりやすく成果を見せてほしかったなあと思います。

This game is difficult as [REDACTED] but once you figure out a pattern, it's incredibly satisfying. Some of the puzzles are outright monsters to handle, even in the first chapter, but still. Sigmar's Garden is one of the best item matching puzzles I've played in a while. 9/10, would recommend.
I thought the UI would annoy me more, but I got used to it
nice
This game is a challenging in the good way. It has programming aspects and a it challenges you by showing you how others did in the level. It even got a story line but I didn’t look into that much. Best 2D puzzle game I ever played.
I got the game about 3 days ago and spent a large part of each day playing it. It's easy to get into as it's a logic game, there's no advanced mechanics maybe other than keyboard shortcuts and understanding how some things function. Out of all the logic games I've played, this one is probably the only one that I can play uninterrupted for so long. Every puzzle can be solved, it's not like you can be given a randomly generated level that might be unsolvable like with Minesweeper (I absolutely despise that part of the game). The controls for the arms are very clear and there's no power creep where you get increasingly ridiculous systems and mechanics that just feel like the devs are coming up with new things to charge their players with (AKA not a mobile game). It's relaxing and you can take everything at your own pace. There's also a pretty big amount of puzzles, the campaign itself I would consider a tutorial for the journal, which is basically puzzles you unlock after beating the game. That's not to say that the campaign isn't enjoyable, but I've learnt so many lessons from it and keep learning more the more journal entries I solve, so now I can go back to my earlier builds in the campaign and improve upon them. The only real negative I can give the game is how irritating it is sometimes to try to figure out a solution. I've learnt of keyboard shortcuts now which are for some reason NOT mentioned at all in game, and everything is far easier to deal with all of a sudden, but say that you're just starting out the game and are making a very long solution with a lot of cycles, you want to check a specific point in time that you believe went wrong, all you can do is press play and wait for it to reach the point you want to check which is SO annoying when you're stuck somewhere and have replayed the same exact spot 5 times already. On top of that, imagine being able to give orders to specific parts of your build while the solution is playing out, as a way to check without having to stop the playback and replay it. Unfortunately this isn't a thing, but worry not, I shall bless the reader with the knowledge that alt+left click plays the build's state on the instruction that you clicked on. It skips the entire playing period up until that instruction. Also, if you select a bunch of instructions, clicking and dragging them while pressing ctrl copies them. These two things are godsent. I'm unaware if they are shown somewhere in the game, but I did not catch wind of them, and neither did others. Get used to the hotkeys for the instructions, get used to the keyboard shortcuts, and your gameplay won't really have any problems. It's very relaxing once the initial frustration at the constant repeats and confusion subsides. That aside, the game also has "Sigmar's Garden", which is another game within it. It's kind of like Mahjong (I haven't played Mahjong in 15 years so this may be wrong) and honestly, I've played and won ~15 games of it and am not really tired of it at all. It's pretty fun and I did not expect it. Overall, good game, I personally play a LOT of competitive games and almost always play multiplayer games, the only logic games I play are usually on my phone when I can't do anything else, but this game actually feels worthwhile. Making my own solutions to these quizzes and then being able to just come back and solve them again if I feel like I can come up with something better is fun. The community is nice and cooperative. You're even given another game within this one. I believe it's worth the price, and if you found it on sale, definitely get it. These Opus won't Magnum themselves.
Fun logic game!
Build mechanisms from moving arms, tell the arms what to do with a sequence of motions. So I guess it's a puzzle game. That's most of the content, but a pleasant cozy vibe overall
