Surprisingly satisfactory to slowly solve the puzzle to bring about a finished production line like a obedient goy. Excellent game!

The content is rich from the get go, and there seems to also be tons of user created missions. The graphics is smooth and the game seems to be well optimized with no issues when tabbing in and out, etc. A very underrated thing about this game is the LOL's when you have later gotten better at it and go back to see how you have created the solutions in previous tasks, oh mein Gott :) "Steam Leaderboards" is enabled and it is as we all know always fun to outclass the fellow gaming pals!

A good puzzle game until it gets frustrating in the later levels. Instead of adding new mechanics they opt for nearly impossible puzzles using the same old stuff.

I love zachtronics games and I think all their other stuff is excellent but unfortunately this one fell short of fun and landed in frustrating.

Pre-Release Review
Posted: June 30, 2015
How to solve a puzzle in Infinifactory:
1) Look at the output and think, "That's not so hard, let me put this here and that over there."
2) Run your experiment.
3) Swear because it's nowhere near what you thought it would be.
4) Swear again.
5) Come up with a rickety solution that works under one use case but falls apart on others. (This is exactly like some real-world programming!)
6) Marvel as your friends come up with more elegant, faster solutions.
7) Realize that you're having a tremendous time.

I don't know what Zachtronics has against the human brain or why he wants to punish it so, but I encourage his behavior. Great game, they've been very good about expanding it and refining puzzles. Recommended.

It's straightforward. The mechanics are simple. The purpose is clear. There's no confusion as to what you are expected to do and what tools you have to do it.

It's diabolical. The puzzles are sometimes bananas, requiring some pretty twisted logic and lateral thinking. While you strive for a solution, there's a constant nagging feeling that sometimes your solution is just inelegant and you need to do it better.

It's oddly darkly humorous. There's a strange undercurrent of defiance against your alien overlords, from listening to the audio diaries of the project managers who came before you, from resenting the food pellets that drop into your cell when you complete sections of the game.

It's also gorgeous - not so much in graphics, which are perfectly adequate, but in the efficiency of the presentation. No main menu. No weird visual effects cluttering up the screen. No unnecessarily ostentatious setpieces. No splash screen! On load, the game drops you right into where you left, so you can literally load the game and get building. There's a gorgeousness to seeing your machine, your factory do its work, and the satisfaction that comes with it makes the effort all the more worth it.

It's one of the most interesting puzzle games I've ever played, and I'm enjoying it hugely despite not being great at coming up with particularly creative solutions.

Early Access Review
Posted: January 19, 2015
This game is freaking awesome. Don't let the Early Access tag scare you, because it's pretty far off, and it's already worth every full-priced penny in it's current state even if the developer decided to walk away tomorrow (which I'm sure Zach will not do)

The best thing about this game (and SpaceChem before it) is the awesome feeling of "♥♥♥♥ yeah, I'm such a badass for doing this ♥♥♥♥", that you get after each level completed. And in a way you are, as this game is a lot harder and smarter than most games out there.

- "I'm such a bad-♥♥♥" feeling
- Great tutorial/intro
- 3 solution slots per level
- Spacechem pyramid dangling in the rear view mirror in the intro
- Learning curve is very well balanced
- Stable and polished

- No in-game recording and sharing tool (ok, this shouldn't be a Con, but we got spoiled...)
- No or too few data points to compare performance (this will turn into a Pro later, as this feature is awesome)

Graphics are functional but nothing to write home about, neither Pro nor Con, but certainly good enough.

I recommend you pick this up at full price if you can, as this is one developer that deserves more money so he can make more good stuff like this. The fact that H1Z1 is topping the top selling list while people put this game on their wishlists waiting for a sale just makes me want to cry. So go ahead and pick this one up sooner rather than later.

Infinifactory does this thing I love. It makes you earn your enjoyment of it.

You load up your next task and take a look at what you'll need to produce and what materials you'll have to produce it with. Immediately, some ideas start popping and you think, "Okay, I know what to do." Ten minutes later, everything's wrong and you realize you were being naive. But you keep building and trying things because that's just who you are. An hour later, things start to click. You still feel dumb as bricks but you're at least smarter than you were ten minutes ago. Then, long after you began, you have a working production facility. You are a genius. The smartest of the smart. Nothing can bring you down from this high.

Then you get to see how your solution rates against everyone else who's finished that same factory and it turns out you're actually pretty much middle-of-the-road. But maybe you can go back and adjust some things and score better? Or maybe you've learned some things and maybe your vision and clarity has leveled up and just by starting fresh you can shave your score by half?

Whatever the case, you have had a blast. You've been challenged for the first time in who knows how long. You've had fun and by all the things that you might even consider swearing on, you've earned that fun.

SpaceChem is one of my favourite puzzle games of all time. I adore its design and its open-ended puzzles. I was interested in Infinifactory because I liked SpaceChem. I was also skeptical. I didn't like the idea of doing puzzles in a 3D space. I didn't like the aesthetic. I didn't like the whole factory concept.

I needn't have worried. Infinifactory is actually probably better than SpaceChem. Which hurts me to say. But it doesn't hurt too much because I'm busy having tons of fun.

I can be very brief about this game:

If you like Zachtronic's SpaceChem, you will like Infinifactory.
If you love SpaceChem, you will love Infinifactory.
If you hate SpaceChem, you will hate Infinifactory even more.
If you think SpaceChem is too hard, you will find Infinifactory undoable.

If you never played SpaceChem, what are you waiting for? There is a free demo available. And if you enjoy it, rest assured that you will enjoy Infinifactory too.

Heartily recommended for all those who love tough puzzles and enjoy building complex machines.

Infinifactory is the kind of game that only a certain type of people will enjoy. I can say that I fall under that category, and I thought it was fantastic. Due to its logical nature, Infinifactory is a game geared toward the same kind of people that enjoy programming; while playing, you'll likely find yourself using a lot of the same practices you might use when coding, such as building machines in "sections", optimizing, and debugging. It's also a great way to know if coding is something you'd enjoy or not; if you don't like this game you probably shouldn't try programming either. The game has plenty of content, and as an added bonus, if you have friends who play the game you can compete to see who can build the smallest and/or most efficient machine (which really adds some good replay value).

Besides the fantastic and unique gameplay, the game has some pretty solid graphics and good, relaxing music. However, there's one thing about this game I find questionable, and that's the story. You've basically been "captured" by "alien overlords" who are forcing you to create these machines for them. Any story that uses those terms is very clearly cliché and uninteresting. Of course, no one is going to play this game for the story, but I think the game would be a lot more polished if the story were to be completely overhauled or even removed entirely (I do in fact like the space setting of the game worlds, and I think the game would work out just fine without any story whatsoever).

Don't let the stuff I said about the story turn you away from playing Infinifactory – it's still an amazing game, and I highly recommend it if you think you're up for the challenge (especially if you enjoy or are looking into programming).

It was included in the Montly Bundle and I wasn't sure I would like it, but then I couldn't stop playing. It was cool to see how my friends solved the puzzles differently through screen sharing on Steam. I was even surprised by the amount of plot. This game is a must play for most people, especially if you enjoy puzzle games.

Absolutely love this game and can only recommend it. Take some parts, figure out how to assemble them to the suggested output and then improve it, improve it, improve it.

For one play-through I spent about 50 hours - and I enjoyed every minute! Fun-levels comparable to Portal, although this is much more tech-y with higher complexity in puzzles.

There are two types of people in the world. Those who play Infinifactory and feel stupid, and those who play infinifactory and feel smart. If you need to feel smart, play this game.
