Description
“It is not an exaggeration to say that without alchemical engineering, civilization would not exist.”

Hailed as the most promising alchemist of his generation, Anataeus Vaya has just accepted a position as Head Alchemist of House Van Tassen, the oldest and richest of the city’s ancient Houses. But dangers lurk behind the family’s opulent facade, and alchemy alone may not solve every problem.

Opus Magnum is the latest open-ended puzzle game from Zachtronics, the creators of SpaceChem, Infinifactory, TIS-100, and SHENZHEN I/O. Master the intricate, physical machinery of the transmutation engine— the alchemical engineer’s most advanced tool— and use it to create vital remedies, precious gemstones, deadly weapons, and more.

Design Machines - Design and build machines that carry out alchemical processes using a variety of components including programmable arms, customizable tracks, and more esoteric devices like Van Berlo’s wheel and the Glyph of Animismus.

Open-Ended Puzzles - Compete against your friends and the world to build the simplest, fastest, and most compact solutions to the game’s challenges. Export animated GIFs of your elegant designs to show them off.

Rich Story - Intrigues and dark plots swirl around the city’s ancient Houses. Alchemists, who hold the power to create almost anything known to science, are highly sought— and highly dangerous.

Solitaire Minigame - Alchemical engineering takes focus and concentration. Take a break with Sigmar’s Garden, an original alchemy-based solitaire game. Every game is winnable, but not every game will be won…

Very Short

I decided to get it to support the dev, since I've enjoyed the other "coding puzzle" games they've released in the past. Unfortunately...I got to the credits in this game in less than two days (it would have been one day if I'd not left the final puzzle until the next day). There is one post-credits chapter which introduces some new mechanics as well as a mini-game using marbles (with no undo button form moves) and a Journal that I stumbled upon while seeking the Options menu that includes an additional 30 puzzles (it's in the right-hand corner of the selection screen, if anyone's looking for it). The Tutorial Stages give you very little thinking to do, but do an okay job presenting the parts and mechanics they introduce. Unfortunately, this does mean the post-credit chapter had items that aren't clear in their use until you've bumbled in the stage itself for a while. The game is missing the "pause" option to put into a code in order to let it play until you're in the segment you want to work at. It has a copy-paste option that requires you to know that you're to hold down CTRL when moving the code to duplicate it, and it is rather painful to move code further along the string, since you are unable to move the code and drag the section for coding at the same time. If you're moving a long bit of code, it is quite easy to accidentally drop it on a code further along and have the game reset it back to its original position. TLDR: Tutorial has only one puzzle where you are not following prompts on the screen. Chapter 1 has 8 puzzles. Chapters 2-4 have 7 puzzles each. Chapter 5 has only 6 puzzles. Post-credit chapter has 11-12 puzzles. [Haven't unlocked the final slot, but suspect that's going to be a closing story segment.] Journal has 30 puzzles. Mini-game has no story elements added after 100 wins.

More than just the main story line

Unless I missed it, no one has metioned the extremely fun puzzle editor. (click icon bottom right corner) .I didn't even know it had this feature for the first 8 hours! It is really fun. You can design your own product and what reagents are allowed to solve it. In the design template, I filled every possible hex with a gold atom and connected them all to see if I could solve it. Yes, but it took over an hour. Best feature of the game. The story is cute and not too hard and like another reviewer, this is the first Zachtronics game I finished.

Surprisingly Fun Puzzle Game

This was one I picked up on sale and just thought it looked interesting. I have found myself playing this way longer than I thought. I even see multiple playthroughs in order to beat my previous times/cost/area. It is a nice game for thought, but doesn't require a lot fo fast reaction. Nice casual game when you want a challenge but not to be on the edge of your seat.

Nicely done done programming/logic game

Fun idea for a logic/programming game. Doesn't teach the programming concepts, but trains the logic and scripting way of thinking.
