To build words you first have to craft each letter in this clever factory puzzle game

pcgamer.com:

If you really think about it, the letter L is just the letter I with another letter I lying down in front of it. What's a T? Maybe two letter Ls that have been welded together after being turned upside down? A V is just an I that's leaning over and has been welded together at the bottom with another leaning I, so an X… that's either two Is crossing each other, or maybe two Vs, one flipped upside down and welded together at the pointy bits. Maybe?

That's the concept in puzzle game Word Factori. You have a small factory that can produce the letter I, and using only that letter you have to create words like OX, CAT, and IVY, and then eventually tougher constructions like DOCTOR, VOXEL, and AXOLOTL.

How do you do it with just an I? Well, by running a production line of Is from one factory to the next. There's a factory that will take an I and bend it into a C-shape, which is naturally how you make a C. But if you want to make an O, there's no O factory. 

So you'll have to get two lines of Is running through a C factory, then flip one line horizontally, then weld them together in another factory. C plus backwards C is an O. And things only get more complicated from there.

Hey, it turns out there was an I in TEAM all this time. In fact, there were a whole bunch of them! My coach was completely wrong.

Half of the fun of Word Factori is simply experimenting. It's not always clear what a factory does until you've run some letters through it, and along the way you might discover the recipe for a different letter than you intended. While trying to fabricate an X for the first time, I sent two horizontal Is into a welding factory and instead of crisscrossing them into an X it instead produced an = sign. Which was not only funny, but
