GK1 Deep Corridor

Normal solution

Hints are given below when you expand the boxes.

Note

This level takes place across multiple floors. In these hints, these floors are named by the words that can be formed on them, if one can be formed. The starting floor is known as the HE floor, followed by the USED floor one floor down, then the TO floor... The ground floor has no blocks on it, so it will just be known as the ground floor.

Spoiler: Hint 1 (what to do)
This is a big one, and very intimidating. Start by examining the level carefully. What is the minimum that you have to do to clear the level?

Spoiler: Hint 2
The ground floor has the exit, guarded by a lot of open bridges to form. How can you make life easier?

Spoiler: Hint 3
Investigate the MUCH floor (two floors up from the ground floor). A feature of the architecture here makes the level a little less scary.

Spoiler: Hint 4
About halfway along the north-south length of the MUCH floor, there's a little outcrop with a pit that drops you onto the path of bridges on the ground floor, past the KINDER bridge. This lets you skip making the word KINDER. (Unless you want the present, of course.) You still have a lot of work to do, though.

Spoiler: Hint 5 (planning and technique)
Because the ledges in this level are so thin, you don't have a lot of room to get behind blocks. The advantage of this is that it's going to be very hard to drop a block from one floor onto another floor. And the blockpads between different floors are very far apart. In other words, each floor is a self-contained puzzle. You don't need to worry about bringing blocks between floors.

Spoiler: Hint 6
All blocks start on their blockpads. If you think you screwed up, you can smash blocks to reset the puzzle state. You might also consider smashing blocks tactically, since you know where they'll end up.

Spoiler: Hint 7

As well as flinging east and west across floors, you may have to fling north and south across their whole length! This means a bit of blind flinging, so try to keep track of where your blocks are, so that you don't fling into them and fall down a floor. (If that happens, all you need to do is die on the spikes on the ground floor and fall back down from the top to where you were. It's not a disaster, just inconvenient.)

Spoiler: Hint 8
The view-squares in the northeast of the chicane of each floor are your friends. Use them to get a view of the whole floor and plan your attack.

Spoiler: Hint 9
If you haven't realised by now, this level is really just five block puzzles on awkward terrain. Treat each floor like any other block puzzle! Once you get over the scale of the level, you'll see there's nothing new being introduced here.

Spoiler: Hint 10 (HE...)
Starting from the top floor, you just need to push the H and E together. How can you push each block? Where do they want to converge?

Spoiler: Hint 11
The H block can only go north or east from where it starts. The E can only go south or west. So getting both blocks into the northeast will be easiest.

Spoiler: Hint 12
Push the H first, then the E Pushing the H into the northwest corner will require you to push it north, then west. This means a bit of flinging between ledges to get yourself into position. Get used to this! Then tuck the E in south of the H to get HE.

Spoiler: Hint 13 (...USED...)

The USED puzzle is probably the trickiest floor of the level if you're not going for the present. Because some blocks are trapped against walls here, though, it should be clear where you want to make USED. (By the way, getting around the blocks here will take a bit of flinging across the width and length of the floor - don't be intimidated, just keep in mind where your blocks are so you don't bump into them.)

Spoiler: Hint 14
The U, D and S are all pointing at the northwest corner. Pushing the U north is a good start. Now work on getting the D out from between the U and S.

Spoiler: Hint 15
Smashing the D to clear a path for the S isn't good enough since it starts on its blockpad and will just respawn right back there. So you'll have to push it east to get it out of the way. That means it will carry the S into the northeast corner. Is that a problem?

Spoiler: Hint 16
The S blockpad is also against the northern wall. Following on from the above hint, if you smash the S, it will now be between the U and D and you can slide it into position!

Spoiler: Hint 17
You can shuffle most of the letters along the north wall to make USED if you're careful Following on from the above hint, the E should just go north across the length of the floor. Then you can either push the D into position or smash it to get it back on its blockpad near where it needs to be.

Spoiler: Hint 18 (...TO...)
The TO comes together like the HE. Figure out where the two blocks want to converge, and make it happen.

Spoiler: Hint 19
Since both the T and the O can be pushed north, making TO on the north wall is easiest.

Spoiler: Hint 20
I hope you can make these diagrams out. Luckily, the two-letter words are simple enough to figure out. Push the O north first, then push the T to meet it.

Spoiler: Hint 21 (...BE...)
The BE floor is the simplest of the lot. You don't even have to touch the E yourself.

Spoiler: Hint 22
You only have to push one block this time! This game must be getting easier. Pushing the B north will get you most of the way there.

Spoiler: Hint 23 (...MUCH...)
The MUCH floor is the other tricky floor here, but as with the USED floor, identifying where the blocks must end up helps you out a lot.

Spoiler: Hint 24
The C and H are trapped against the east wall, and the M and U can both be pushed east to that wall from the start. So you'll be writing MUCH north-to-south along the eastern ledge.

Spoiler: Hint 25
The M will end up in the corner next to the view-square. Then you have to get the H out of the way so that you can bring the U to the M.

Spoiler: Hint 26
The H will have to go south (taking the C with it) so that the U can go east and north to the M. The C gets sent to the southeast corner of the level, but that's okay, because...

Spoiler: Hint 27
Oh jeez, it's getting tougher again ... you can smash the C to spawn it directly south of your MU. Then it should be easy to get the C in place, followed by the H, and close the last bridge to the exit! (Remember, you can drop down through an outcrop of railings on this floor to skip the KINDER bridge!)

Spoiler: Hint 28 (full solution)

On the HE floor (the starting floor), push the H north and west, then push the E west and north to make HE reading north-south. (See Hint 12 for a diagram.) On the USED floor, push the U north, push the D east (catching the S as it goes), smash the S, push the new S west, push the E north, then push the D west to make USED. (Diagram in Hint 17.) On the TO floor, push the O north, then push the T north and east to make TO. (Diagram in Hint 20.) On the BE floor, push the B north and east to make BE. (Diagram in Hint 22.) On the MUCH floor, push the H south (carrying the C with it), push the M and the U east, smash the C, and push the H north (which will push the other blocks north with it and make MUCH all at once). (Diagram in Hint 27.) Drop down through the railings on the MUCH floor directly to the bridges on the ground floor to skip the KINDER bridge, and follow the bridges to the exit.

Present solution

Spoiler: Hint 1 (present location)
You can find the present at the bottom of the pit, next to a KINDER bridge.

Spoiler: Hint 2
You only need to spell KINDER on the second-to-bottom layer if you are going only for the present. Solve the other words as well if you want to exit the level.

Spoiler: Hint 3
A quick drop down from the start along the KINDER column will bring you to the right floor.

Spoiler: Hint 4
The procedure is similar to the other floors, except more complicated. Note that some letters have multiple block pads. Use the view squares to get the layout.

Spoiler: Hint 5
Most of the blocks start along the east side, so you probably want to build the word along the NW wall (why else would there be blockpads there?)

Spoiler: Hint 6
Some blocks necessarily get stuck in corners but you can smash them to rebirth them on a different block pad. They will be reborn on whichever pad is closest.

Spoiler: Hint 7 (solution)

Uh, it might be easier to follow the written instructions here. But this is how you'll be shuffling the blocks around on the KINDER floor. We'll spell KINDER vertically along the south end of the NW wall (near the I, D, E block pads). Working in reverse order: Position R: Along the north wall, push R west, smash it, it will rebirth a bit to the south, push south into the corner. Position E: Along the south wall, push E west, smash it, it will rebirth a bit to the north. It will collide with the D and fall down. Drop down and smash it to rebirth in place above the R, making ER. (You could push the D west first to save falling down but for simplicity I'll try to just move one letter at a time.) Position D: Along the north wall, push D west, smash it, it will rebirth a bit to the south, push south making DER. Position N: Along the east wall, push N north, smash it, it will rebirth a bit to the west, push west, south making NDER. Position I: Along the north wall, push I south, east, smash it, it will rebirth a bit to the north, push north (picking up the K along the way). Smash I, it will rebirth a bit to the west, push west, south making INDER. Position K: Along the east wall, (assuming you already pushed it north in the step above), smash it, it will rebirth a bit to the west, push west, south making KINDER. Jump down into the pit to and take the stairs on the south side to the present.

Extras

Spoiler: Achievements

There is 2 achievement available for this level: Deathless Depth: Beat Deep Corridor without dying. Spoiler: Hint 1   The only spikes are on the bottom floor, so you will only die if you land on them accidentally or need to reset yourself to the top of the tower. Spoiler: Hint 2   Therefore, you need to complete each floor before moving on to the next. Spoiler: Hint 3   You don't need to make the KINDER bridge to get the achievement. Spoiler: Hint 4   Follow the exact solution as solving the puzzle normally (see above). Just be careful not to fling yourself into a block and fall down accidentally. Much Deeper: Beat Deep Corridor without spelling "much". Spoiler: Hint 1   Look at the layout of the walls on the bottom of the pit. If you are not spelling MUCH, there must be some way to get on to the center walkway past that. Spoiler: Hint 2  On most floors, you can't get letters off their floor. However, on the KINDER floor, some letters can collide and fall down further. Spoiler: Hint 3  Specifically, there is a row with the I block pad on the west, and the K, R, N blocks on the east, all in a line. Spoiler: Hint 4  If a block dropped down immediately east of the center-west I blockpad, it would give you a place to get on to the USED bridge below. Spoiler: Hint 5  Make the HE and USED bridges as normal (see normal hints 10-17). Drop down to the KINDER floor. The N will get in the way later so push it west, south out of the way. Get the I to the center-west blockpad by pushing it south, east, smash it, push north, smash it. Smash the K to put it in line east of the I. Push K west so it drops down next to the USED bridge. Fling west following the path of the K and step up to the bridge and the exit.

Spoiler: View squares
There are 7 view squares on this level: 1 on HE level in NE corner. 1 on USED level in NE corner. 1 on TO level in NE corner. 1 on BE level in NE corner. 1 on MUCH level in NE corner. 2 on KINDER level in NE corner.

Spoiler: Hanging men
There are 1 hanging men on this level: Along the north wall, on the top (HE) level.
