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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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.

The little eureka moments as you think of ways to make your solutions smaller, cheaper and faster is fun. And it's nice that the game doesn't give you any constant rewards or goals, it's all up to the player. I've played other similar games where the game says something like "Solve the puzzle in less than 132 cycles for a gold medal" which feels frustrating, like you need to copy the designer's exact solution to win the game. But this game feels rewarding and fun, and it's up to you how much of a perfectionist you want to be.
Tickles your brain in a really good way

好玩 至于什么周期成本面积,能动就是我赢了!
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
Fun logic game!

lovely puzzle game
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.
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.
Mechanically deep puzzle game that has no true right or wrong way to play it with some of the most difficult puzzles I've seen in a game. Very fun and satisfying.
