Grog see game with shiny colored beads and ticky tock wheels. Grog try to string shiny color beads in right shape, but Grog not smart and it make Grog head hurt. Grog solutions take too many cycles and look like Grog ass. Maybe if you smarter than Grog you like this game.

I have not completed this game, I may never. I Play Opus Magnum when I want to feel smart, I almost always end up wishing I actually was. I have as much fun rebuilding and improving my finished machines as tackling the next problems. I can't wait to try Zachs new game. If you enjoy problem solving, denial & error building and watching dominoes fall, then this is a game for you.

Have you wanted to do alchemy, but also play factorio at the same time? Well, this is a game for you. It has pretty good and challenging puzzles, the story is interesting - and as every zachatronics game, there is also a board game built in for when you need a break.

One of the greatest puzzle games of all time. I played tons of "The Codex of Alchemical Engineering" and "The Codex of ALchemical Engineering: Magnum Opus Challenge" (the flash game versions of this) back in the day There are some aspects of the flash game that I prefer: tracks and unlimited instructions on each arm make just solving a lot of puzzles too easy, and the automatic padding of all instruction sequences to be the same length is kind of annoying That said, tracks and unlimited instructions really shine in harder puzzles, or if you try to go for a lowest cost challenge. Each puzzle has almost unlimited replay value if you try to minimize cost, cycle etc. I managed to solve Refined Bronze with one fixed length arm and 4 tracks, and I thought that was probably optimal, but it's been done with one fixed arm and no track! Also, the full version of the game uses a hex grid instead of the square grid from the flash game, which is a big improvement The production alchemy puzzles are my favorite, because the space constraints make them interesting even if you don't go for an optimized solution. It's also fun to try to do them with only one chamber. I wish there were puzzles with some other mandatory restrictions like limited instructions The journal also includes 45 more puzzles, which are generally harder than the story puzzles. There is even a new element (quintessence), a new version of sigmar's garden including that element, and some tougher production alchemy puzzles. I really like the out of the box production alchemy puzzles, ie the ones where you just have to disassemble and reassemble the same molecule, or the one where there are no bonders or unbonders The music is really good, and the story is cute, it's obviously just flavor and I like the journal puzzles more, but I'm glad the story was added A couple control tips: hold "1" to display "ghost atoms" (where all the molucules were the last time you stopped the simulation), hold "3" and click an instruction to fast forward to it (this is insanely useful), ctrl + click + drag to COPY selected instructions or even parts (you can select multiple things with click + drag, and add to a selection using shift + click (+ drag)), pan by right click + drag (you can also shift + scroll to pan the instruction pane), and finally you can change controls so that the keyboard shortcuts place an instruction on the selected track instead of needing to click too

1. Simple story inferred through brief sections of dialogue. It manages to connect the puzzles together, if you're looking for a little narrative depth, but it's also not necessary or overbearing. 2. Puzzle concept is original and robust 3. No artificial difficulty; no timers, obfuscation of rules, or harsh restrictions; just increasing complexity of solutions, and letting you set your own goals of how you'd like to compare to the other players stats. Make cheap machines, or faster machines, or smaller machines, its your choice. 5. Graphics are stylish and satisfying 6. User Interface (for solution planning) isn't as polished as it could be, and you'll fight to manifest and troubleshoot a new idea quickly, especially on the bigger solutions, but that's hardly a dealbreaker considering everything else.
