You start off facing the door of the barn, locked of course. There's a lock next to it with four dice faces in a grid. (I guessed this code on my first playthrough and finished the game instantly, so I had to replay to free the pigs.) To the left of it, a pig is locked in a cage, together with the end of a stick and probably whatever's on the other end. The lock has six symbol buttons in a grid. Above the cage and next to the door, there's a rather insignificant window which (spoilers) is actually rather significant.

Turn around, and your field of view is now closer. The three windows on this screen have their top and bottom sides colored red, green and blue. They also differ from the other sides in that you can see the grain on the wood. The blue window has some blue markings covered up with dirt. There are also a cabinet that looks like stacked boxes walled in, or rather planked in, inside a pen. And of course, there's a pig locked up in another pen with a lumber saw. The lock for this pen has three buttons that cycle through different green arrows when clicked, four counter-clockwise arrows from lower-right and then four clockwise arrows from upper-left.

Head out the side door and take a look at the yard, which has some annoying weeds growing in the center among the neater grass, as well as three less annoying groups of yellow metal bars in the fence among the silver ones. There's a water trough on the right, and on the left there's also a pig locked in a cage with a broom. The lock requires a sequence of three colors.

It should be clear which of the three pigs to save first...

Use the colors of the window planks to unlock the cage in the yard.

Make the buttons red, green and blue (1, 2, 5 clicks), then click OK.

Click on the pig to free it (and get a cutscene!) and then pick up the broom.

Use the broom on the weeds, leaving three curved hoof tracks which you can click on to zoom in.

Use the clue from the hoof tracks to unlock the pig pen.

It's too confusing for me to type out, but just click the buttons 4, 3 and 2 times.

Open the pen, click the pig (cutscene!) and then pick up the saw.

Hmm, there are no trees here. Instead, cut down the colored planks from each window, as well as the long planks below those.

Those were conveniently covering up two locks on the cabinet, which now you have to solve. The top drawer lock needs a three-digit code (in bright yellow digits!), and the bottom drawer lock needs a sequence of red, green and blue buttons.

Use each of the pairs of colored planks on the long planks to put together a ladder. But there' no way to attach the ladder planks together yet, and the planks are all jumbled up.

...twice the code. Use the colors from the ladder to unlock the bottom cabinet drawer.

From top to bottom, the planks are Red Blue Red Green Green Blue.

So click the CLCRRL buttons, and open the drawer to get some nails.

The groups of yellow metal posts form the clue to unlock the top cabinet drawer.

There are 5, 4, 1 posts in each group.

So enter that in the drawer, open it and take the cloth.

Use the cloth on the water trough, and then use the wet cloth on the dirt on the right window (which was blue).

This reveals a code with the silhouette of a pig head and a path that takes four angular corners and ends in an arrow.

Follow the path from the window to press the buttons on the other pig cage in the right order.

Press the buttons in the following order:
146
235
and then open the cage, pick up the last pig, and take the hammer behind it.

Use the nails on the unfinished ladder and then the hammer. Now you have a working ladder!

(Don't try this at home, especially if you only have six nails.)

Place the ladder under the window on the first screen, climb up. Oddly enough, you can't see anything through this.

Use the hammer to smash the window. Now you can see loads of houses on the hilltops.

Count the houses visible through the window and use that clue to unlock the barn door.

The houses visible through each pane number
2 2
3 4

Enter that (1, 1, 2, 3 clicks), open the door, and walk out with the pigs!

Note the two sandwiches showing in the picture to the left.

Solve the diagonal puzzle

Look at the tomatoes.

Look at the ketchup and mustard containers

Look at the diagram of the three eggs.

The light green letters are UCUMIEI.

Enter the numbers from the cucumber.

Enter the colours of the peppers from the picture in the second room.

Click on the letters on the hamburger patty in order.

Look at the mayo jar.

Set the pictures to match the picture of the onions.

Match the location of the cheese in the puzzle with the cheese in the pictures.

Look closely at the bread knife.

So once again, Amajeto Hotel has left you to clean up the room for them. Pick up three golden squares on the couch, next to the telephone and next to the lamp. In the process, you'd probably noticed that the phone's display only has room for five digits, and that the each of the orbs on the lamp lights up a different color and hangs by a different number of threads. Of the three pictures hanging over the sofa, the center one looks messed up and the ones on the sides can be flipped over. But only the one on the left has a clue on it when turned over: a single blue diamond. There's a compartment under the right picture that you can't open yet.

Turn right. The balcony door is locked, so turn right again. The wall here is decorated in a familiar way: four safes under four rectangular sections, and a TV in the middle over some books and a box. Take two golden squares from on top of the box and next to the vase on the right. You don't have a remote for the TV and don't know what the numbers on the top and bottom of the books are for (yet), so look at the four safes. The first safe on the left needs a four-letter code. The second needs a sequence of small and large heart buttons. The third needs a code of four card suits. The fourth needs a four-digit code.

Turn right. The wardrobe on the right side is locked and needs a 4x4 grid of colors, either white, yellow, green or orange. Go down the entry corridor and check out the picture with tilty corners on the left wall and the completely boring room door and the grid panel on the other corridor wall with a white box on the right side and a slot on the left. Pixel hunting, yay!

Click each piece to rotate until the picture reforms. (It's randomized each time, but try to match the middle pieces along the horizon line, and then the corner pieces to the left and right pictures.

The compartment under the right picture opens up. Take the golden square.

Use the numbers on the books to unlock the tilty corner picture.

The numbers are:
12____3
45____6

So click the corners in that order (⌜⌜⌝ ⌞⌞⌟), and the picture slides down. There's another compartment which you can open up to take another golden square. Also turn the picture over to see a four-digit code and a diagram of a keypad.

Enter the code from the tilty picture to the phone.

Enter 7105, and then press the green E key, turning the digits green. Wait, that didn't unlock anything!

Hint: which other safe has its code in green?

Turn the green 7105 digits into four green letters for the first safe left of the TV.

Turn your screen, or turn your head, and the digits read SOIL.

Enter that, open the safe, and take a remote control and golden square.

Turn on the TV. It's even more boring than before, displaying just the word HearT over a yellow heart shape.

Unlock the second safe with the TV clue.

The first and last letters of HearT are capital (large), so that the letters are large, small, small, small, large.

So click the RLLLR buttons, open the safe and take the key and golden square.

Use the key to unlock the balcony door and go outside.

A breath of fresh air, enjoyed against a pixelated night sky.

Take the golden square from the table, which also has a yellow-green-yellow stripe of squares running across the upper-right. The lift the bowl to see a green club suit painted underneath.

At this moment, a strong breeze blows by and you can't help but squint, and you spot something interesting about that building in front...

The lit windows on the building form the digits 5213, underlined by the bottom row.

This gives you the inspiration to go back in and unlock another safe.

Unlock the rightmost safe with the digits from the office building outside.

Enter 5213, and open the safe. Take a golden square and a rectangular device with a big red button on it. Notice the red spade suit on the back of the cupboard.

Use the four card suit clues from around the room and the clue from the lamp to unlock the safe just right of the TV.

Lamp colors, from top to bottom:
1 string , blue
4 strings, green
3 strings, yellow
2 strings, red

Which suits were blue, red, yellow, green?

Suit colors:
Blue diamond (back of picture above sofa)
Yellow heart (TV)
Green club (table outside, under bowl)
Red spade (4th safe)

So 1234 = BRYG = DSHC. Enter Diamond, Spade, Heart, Club into the safe, and take a golden square from inside.

Use the button device on the slot on the left edge of the corridor grid panel, then press the button.

The squares glow yellow and green, and orange if you zoom out and look at it. But three of them are still white.

Combine the corridor grid and table color codes to get the code for the wardrobe lock.

(None of the sixteen squares should be white.)

The colors are (Yellow/Green/Orange)
OYYG
YOGY
YGOY
GYYO

So click each square on the (yellow) edges once, the (green) LL-UR diagonal twice, and the (orange) UL-LR diagonal thrice.

If you have it correct, the door swings open and you can take the last golden square. (Examine it in your inventory to make sure.)

Now that you have all 13 golden squares, use them on the square grid.

You have to swap pieces on the grid to form a picture of butterflies. This puzzle is also randomized, but here's a hint: the lightest part of the picture is near the upper left.

Once you have it correct, the box on the side should open up for you to take the door key. Use it on the main door to escape!
