Deadlocked

Deadlocked is the twentieth and currently the last official level of ''Geometry Dash. As of ''Update 2.0, it is the last of the three official levels that are rated Demon so far. It can be unlocked upon collecting 30 secret coins.

Description
Deadlocked shows a variety of new map components. Most notable are the green jump rings which reverses the character's gravity and adds momentum. This is the equivalent of hitting the blue and yellow jump ring at the same time or hitting a yellow ring in a blue or yellow gravity portal. It also showcases the teleportation portals, in which you enter a blue teleportation portal, and exit through its corresponding orange teleportation portal. The colour of the teleportation portals assume a Portal reference. There are also moving blocks, which were introduced in the previous level. The most attractive part of the level is at the second UFO sequence, when monsters appear, shooting lasers, which is similar to the laser parts in the popular mobile game Jetpack Joyride.

Secret Coins

 * The first secret coin is unique compared to others, as it requires a key before it can be acquired. In the first ship sequence, a key is placed high up above the moving squares at 19%. Once successfully retrieved, it opens an area in the fourth cube sequence which allows the player to grab the coin at 43%. Failure to retrieve the key will keep this passage blocked and the player will be forced to take the normal route situated below it.
 * However, there is a glitch where you don't get the key, brush past it, and still be able to get the coin.
 * The second secret coin appears at 52% during the second Robot sequence. There will be a two-block wide pillar sticking out from the ground. Instead of flying to the top of the pillar, you must drop down and jump shortly after to collect the coin. To return to the normal path, you must jump on top of an invisible block. This is considered slightly easier than the normal path.
 * The final secret coin appears exactly two-thirds of the level (66%) During the second UFO sequence, there a monster shooting lasers at the player. Before the first laser is fired, try to get close to the top. There will be a saw blade, tap twice quickly or just tap once because you don't want to crash into the ceiling, wait a second and tap again, the coin will be acquired. If you do tap twice to start, get right in front of the laser and tap twice the millisecond before it is fired. Try to get down quickly as there will be another round of lasers fired shortly after.

Trivia

 * This is the first and currently only official level to award 15 stars upon completion.
 * Deadlocked is the official level that features the most speed portals.
 * Deadlocked is the first official level to intentionally introduce the antigravity wave.
 * However, in Blast Processing, after the first ball segment, the blue deactivation gravity portal on the wave may be skipped if you hold right before entering the portal, thus making the wave travel in antigravity. Also, there is a small chance at the end of the dual wave section at around 53%, that the anti-gravity copy of the wave will enter the blue dual deactivation before the real one. Thus, Blast Processing is technically the first level to have an anti-gravity wave.
 * Also, it is possible to jump on the yellow pad en route the first secret coin in Geometrical Dominator, causing you to miss the blue pad. You will play the ship and the wave in antigravity.
 * Both of these routes are detrimental, as you will fall out of the world in the cube segments after the wave segments
 * However, the 2 errors in Blast Processing cancel each other out.
 * The platforms in the first cube light up whenever the player contacts it, activated by "Pulse" triggers.
 * At the beginning of the first ball sequence, there are two blocks, one with a blue glow and a checkmark above it, and another with an orange glow and an X above it. These mark which platforms are safe and which are fake (a monster crashes the ball if you try to land on it).
 * Deadlocked is the second level to feature a triple speed portal. The first was Electrodynamix.
 * It is also the first level to have multiple triple speed portals (four in total).
 * Deadlocked has the earliest form change, changing to a mini wave within the first seconds of the level.
 * It also has the shortest segment of a certain form, with the first mini wave segment only lasting around 0.75 seconds long.
 * This is the second level that does not have a coin in its ship sequence. The first was Electrodynamix.
 * However, the key to access the first coin is collected in a ship sequence.
 * This level also makes an interesting use of moving objects and monsters to create "enemies" in the second UFO part. The monsters appear to follow the player, shooting "lasers" from their mouths that the player must avoid. This is similar to the lasers in the game Jetpack Joyride.
 * It takes 1:39 to complete the level.
 * Deadlocked is the second level where you can transform in every currently available form, the first one being Geometrical Dominator.
 * This is one of the four levels where you barely touch the ground after the beginning, the other three are Hexagon Force, Clubstep and Geometrical Dominator.
 * This level and Geometrical Dominator are the only levels after Blast Processing to not include a Secret Coin in a Wave segment.
 * This is the first level where the ground color only changes once. The ground stays black after the first wave sequence.
 * In this level, more specifically at the second set of teleportation portals, there is a glitch where if you hit the green ring before the TP portal late, it's possible to hit the yellow ring following without being in anitgravity, shown in this replay: here
 * This is the only level after Theory of Everything that not contains purple rings.
 * This level uses every portal available except for the mirror portal.

Decorational Errors

 * When you crash at the last green orb at the second cube sequence, you can see that the top areas to the left and right are unfilled.
 * In the second cube section at around 6% to the bottom-left of the orange teleportation portal, the edge of a diagonal spike is missing.
 * In the last ball sequence, single "orbs" can be seen at the top and bottom of the level. But in the middle of the ball sequence at the top, two of those "orbs" can be seen overlapping each other. This may or may not be intended.
 * One of the orbs was also replaced with a pad, although this was meant to kill the player, and hence the player must jump over it.

Structural Errors

 * In the first cube segment you can go on the third antigravity jump ring (the first right after the mini wave) and continue normally.
 * If you notice, the second orange teleportation portal has a yellow jump pad peeking on the left of it. This is use to initiate a jump to reach the next orb.
 * At 8%, you can jump over a gravity pad instead of hitting it and continue the level by hitting the gravity ring.
 * At 9%, if timed correctly, after going through the teleport portal, it is possible to hit the yellow jump pad before touching the gravity portal, therefore causing a crash.
 * After going through the second teleportation portal at around 9%, the jump ring marked with an "X" can be hit with precise timing and not make the player crash.
 * If the player goes through the second teleportation portal late, then they will be forced to hit this jump ring and doing this will always result in a crash.
 * It is possible to collect the first coin without the key. This can be done by going slightly under the key, so close to it that the path with the coin will be accessible. This happens because the key has a smaller hitbox than other touch triggered objects, so the toggle object is triggered without actually getting the key, as shown here.
 * During the mini ball segment, at 37%, you are able to skip a teleport portal and a green ring if timed right, shown here.
 * In 2.01, this was "patched", but it is still possible, just much harder now.
 * At the first robot segment, you can skip a gravity portal and a teleportation portal by holding longer.
 * During the first mini cube sequence, if you hold down instead of hitting the last gravity ring before the teleportation portal, you will fall towards the orange teleportation portal, hit a jump pad hidden in the portal, and continue as normal.
 * At the first teleport portal set after the first secret coin location, it is possible to hit the first gravity ring and survive by landing on the edge of the pillar, despite the pillar having spikes on it.
 * Around the second secret coin area, RobTop has left an "alternative route". After falling down from the pillar into the secret area as normal, instead of making a small jump to reach the coin, make a large jump, but don't touch the green orb. If timed correctly, you will realize that you can enter a overhanging pillar (with fire on both sides), as it is hollow. You can carefully jump off this pillar and continue normally, although this won't do anything.
 * It is also possible to get the 2nd coin while tapping on the green jump ring. However, this will kill you if you collect the coin.
 * Sometimes, making a very small jump before hitting the green orb will cause the player to propel in a certain direction to obtain the coin but land safely and not die.
 * Jumping too late into the third teleportation portal in the level can make the player crash.
 * Sometimes, during the first ball segment, hitting the first orb too late will cause the player to go too high up, activating the first monster trap (on the orange blocks), but not killing the player. They will then be forced to hit another orb, which will immediately cause the player to crash by throwing them into the second monster trap.
 * During the first ball segment, if you hit the first blue orb late, you will skip the move triggers and the platform will not appear. However, this will result in a crash.
 * After the 2nd coin, you can skip the green and blue orb.
 * At 1%, if you hit the second gravity orb late, you can skip the yellow jump pad, jump up from the very edge of the platform and continue safely. However, this will require precise timing.
 * At 9%, if you hit the green jump ring early, it is possible to miss the yellow jump pad and crash.
 * Exactly at the second ball segment, it is possible to flip gravity right before the yellow jump pad. Flip gravity again and you can continue safely.
 * If timed correctly, one may go through the wall in the first wave segment as seen here.
 * At the first ball segment, if you hit the last green ring late, you can do the mini-ufo segment upside down.
 * At the mini ball segment at 36% hitting the green orb to the teleportal after the normal speed too early will make you crash on the blocky spikes before the orange teleportal.

Patched Errors

 * Just before the second wave segment, if you hit the last green ring before the wave portal a bit late and hold your jump key, you might be able to play the sequence at a normal speed than a triple speed and the music will be out of sync. A similar error is found in Theory of Everything 2, however, in Theory of Everything 2, the erroneous path was detrimental, where as this error is beneficial. This and the related errors were patched out in update 2.01, with the portals made bigger and sawblades placed at the start of the segment.
 * It is also possible to get a similar error in Hexagon Force, though it is quite hard to do so. Once again, this error is detrimental.
 * Also, if timed correctly, hitting the second last green orb in the first cube part and missing the last green orb would allow the player to slide up an upper slope in antigravity in cube form and go through the wave segment, but you will crash against the lower slope when you reach the antigravity portal, as seen here. However, if you make a series of perfectly timed jumps, you may be able to continue the wave segment as a cube and then continue the level normally. Jumping early and hitting all the gravity portals will allow the player to survive and head straight to the normal ship sequence. However, this will shatter the synchronization of the music.


 * At the first ball segment, it was possible to slip under the ball portal and remain as a mini ship.
 * If you survive through the ball sequence, it was also possible to go through the UFO sequence as a mini ship too.
 * This was fixed in update 2.01.
