->''"Elephants sometimes do forget... the rest of the levels."''
-->-- Slogan for ''This Is The Only Level''

''This Is The Only Level (Adventures in Singularity)'' is a game created by Creator/{{jmtb02}}. It features an elephant, trying to escape a room. That's all the game is.

Or so you would think.

Actually, there is only one level... but you have to repeat it, over and over. And each time you finish it, the aspect of the levels change. There are thirty variations of the level (called stages) in all, and each of them are different.

It can be played [[http://armorgames.com/play/4309/this-is-the-only-level here]].

A sequel, ''This is the Only Level TOO (The Heroic Quest to Complete Another Level)'', is [[http://armorgames.com/play/5351/this-is-the-only-level-too over here]]. ''This is the Only Level 3'' is [[http://armorgames.com/play/12745/this-is-the-only-level-3/ here]]. ''This is the Only Level 4'' is [[http://armorgames.com/play/14694/this-is-the-only-level-4 here]].

The same elephant stars in ''VideoGame/AchievementUnlocked'' and its sequel, as well as ''[[http://armorgames.com/play/1719/elephant-rave Elephant Rave]]'', ''[[http://armorgames.com/play/3102/run-elephant-run Run Elephant Run]]'', ''[[http://armorgames.com/play/4987/obey-the-game Obey The Game!]]'', and ''VideoGame/ElephantQuest''.

!!All four levels provide examples of:

* DoorToBefore: The exit of the level takes you back to the start of the level.
* ExactlyWhatItSaysOnTheTin: There IS only one level in all four games. You just have to do them loads of times (one level, but different ''stages'').
* FakeTrap: In the first level, the spikes in "Dull appearances" [[spoiler:act as springs]]. In the second, they have different properties in "Left IS Right" ([[spoiler:the bottom of the row of spikes on the left wall is fake]]), "On Ice" ([[spoiler:all the spikes disappear when you go near them]]), and "[=D34TH=] 15 2AD" ([[spoiler:you have to make certain sets of spikes disappear in a certain order]]). Otherwise, they kill you.
* IdiosyncraticEpisodeNaming: The titles of each stage contain a clue as to how to solve them.
* InterfaceScrew: Some of the stages in all four levels either reverse your controls or disable certain buttons. Some of them even make you use entirely new keys.
* InvisibleBlock: In the first level's "Mime's folly", there is [[spoiler:an invisible wall to the right of the button that you have to jump over]]. The second level features "[[PunBasedTitle Amazeing]]", which is [[spoiler:a maze made up of invisible blocks]].
* JumpPhysics: The '''''elephant''''' (and the secret characters in the sequel) can jump like freaking [[SuperMarioBros Mario]]. Sometimes.
* LockedDoor: In [[spoiler:almost]] every stage of all three levels. Sometimes figuring out how to open it is part of the stage puzzle.
* PressurePlate: The button that [[spoiler:sometimes]] opens the door.
* SideView
* SolveTheSoupCans: Admittedly the hints are there in the titles but the solutions are still pretty far out.
** For Level 1 in particular, "Time to refresh" requires you to [[spoiler:''refresh the page'' in your browser]] to unlock the door (though an updated version of the game changes the title to "Refresh or Panic" and lets you [[spoiler:hit the [[PressXToDie panic button]] instead of refreshing]]), and "Credit page" requires you to [[spoiler:go back to the menu, then go to the Credits page and click "Main menu, and unlock Stage 27 for me" there]].
** In Level 2, "Peek-a-boo!" requires you to [[spoiler:face away from the door to open it, then dash through before it closes again]], "Stuck?" requires you to [[spoiler:click the walkthrough button]] to unlock the door, "Deaf, Dumb, and Blind" not only requires you to navigate the course [[BlackoutBasement while blacked out]], but also [[spoiler:hit the Mute button]], and "What's On The Menu?" requires you to [[spoiler:go back to the menu, then control the elephant in it and bring it onto the button at the top left, and return to the game]].
** Level 4's "Healthy Teeth" requires you to [[spoiler:clean the walrus's tusks on the main menu]].
* SpeedRun: Required in the third and fourth levels to unlock [[PlatformHell FML Mode]] (which stands for "Frustratingly Manipulative Level" or "Friendly Memorable Love", [[BlatantLies apparently]]).

!!Level 1 provides examples of:

* DoomyDoomsOfDoom: The "Candy stripes of doom" stage.
* EverythingBreaks: In the "Collapse" stage.
* SchmuckBait: The button in "Think before doing" [[spoiler:closes the already-open door.]]

!!Level 2 provides examples of:

* AndNowForSomeoneCompletelyDifferent: Stage 9 has you controlling [[spoiler:a donkey]]. [[spoiler:This is inverted when you actually unlock the donkey as a playable character. Going back to Stage 9 does nothing, but going to the stage after that has you play as the elephant instead.]]
* ContinuityNod: The "stage cleared" message for the final stage is "But is the level over?", which was the only message for clearing the stages in Level 1.
* [[spoiler:DescendingCeiling]]: Stage 14.
* [[spoiler:EverythingsBetterWithDinosaurs]] and [[spoiler:NuttySquirrel]]: Two of the secret characters.
* FakeDifficulty: The ''only'' type of difficulty in FML mode, which derives its challenge from putting the player in frequently {{Unwinnable}} scenarios and insurmountable odds.
* {{Letters 2 Numbers}}: Stage 27: [=D34TH=] 15 2AD.
* LuckBasedMission: ''Any'' stage easily becomes this in FML mode due to the randomly-generated extra bits of level, since all too often the position of said bits makes the level {{Unwinnable}}. Sometimes they even block the exit.
* MinusWorld: [[spoiler:The EasterEgg and AscendedGlitch from the previous game. This also applies to level 3.]]
* PlatformHell: FML Mode (FML is an acronym for "[[ExactlyWhatItSaysOnTheTin Frustratingly Manipulative Level]]"). It is ''not'' UnwinnableByDesign (determined players have completed FML mode), but it comes oh-so-close.
* RougeAnglesOfSatin: The beginning of the ending text says "You have '''beat''' the only level in the game." [[http://www.youtube.com/watch?v=YX51tpjO9Wk Tasselfoot's video walkthrough]] shows a version of the game where the clear message for Stage 12 is "But '''your''' still trying to find the ending."
* ShoutOut: There are two references to ''SuperMarioBros'' -- the clear message for "Red Light!" is "But the end is in another castle.", and Stage 11 is titled "World 1-2" and [[spoiler:requires you to hit the top of the level to reach a warp zone on the other side]]. Also, the clear message for "Sliding Portcullis" is "But {{will it blend}}?"
** There is also another one to another of Creator/{{jmtb02}}'s game, ''VideoGame/AchievementUnlocked''; stage 28, Surface Painting, has you coloring the surfaces.
* SpeedRun: Required to unlock the secret characters.
* WarpZone: [[spoiler:In Stage 11. All three pipes lead to the same level you've been going through.]]
* WhereItAllBegan: [[spoiler:Stage 7 makes you return to the starting pipe.]]

!! Level 3 provides examples of:
* AWinnerIsYou:
-->YES! You win!\\
NO! We don't have anything awesome to give you\\
BUT... maybe we could assign you some random title
* ArtShift: The background and blocks are much more detailed than in the first two levels.
* AndNowForSomeoneCompletelyDifferent: Similar to the second level, one stage has you controlling a Raptor.
* BulletHell: Stage 15. And [[spoiler: every stage in [[PlatformHell FML Mode]]]].
* FunWithAcronyms: In stage 14, you are supposed to spell "Blue". The name of the stage will abbreviate to [[spoiler:B.L.U.E]].
* SchmuckBait[=/=]CallBack: A reference to the first level, Stage 21's switch [[spoiler:closes the already-open door]].
* ShoutOut: The clear message for Stage 3 is "But [[StarWars are these the droids you are looking for]]?" Stage 11's is, again, "But [[WillItBlend does it blend]]?" Stage 6 is called "[[LordOfTheRings Speak Friend And Enter]]". [[BulletHell Stage 15]] is called "The VideoGame/{{Touhou}} Project", and invokes ''{{Ikaruga}}''.
** More references to previous elephant games: stage 9 is based on ''Elephant Rave''. The pastries first appeared in ''AchievementUnlocked 2''.
* UnexpectedGameplayChange: [[spoiler: To get through Stage 27 you have to play a game of ''Videogame/{{Snake}}'' in the corner of the high scores screen]].

!!Level 4 provides examples of:
* OddballInTheSeries: Unlike the other levels, this one is designed entirely by Tasselfoot. As a result, there are various departures from the previous games. The main character is a green walrus, the "You Win" messages do not begin with "But...", and [[ArsonMurderAndJaywalking the Armor Games logo retains its music and sound effects rather than overriden by the game's main music]].
