Clutterfunk

Clutterfunk is the eleventh level of Geometry Dash. It is the second level to be rated "Insane" as of Update 1.9.

Description
Clutterfunk is often regarded as one of the relatively harder levels. It has many traps and introduces new obstacles, sawblades, and smaller spikes. Some of them are the mini ball tight timings, the "hall-based" rocket segments, and the mini cube sequences. This level added more aesthetics such as the gear-like decorations and introduced two new block variants.

Clutterfunk also introduces the size portals which either shrink or enlarge the player's icon in the different forms, which make the player jump at a different height depending on the size. The speed of the player does not change when changing sizes, even though the mini cube looks like it is going faster than the normal sized cube.

Secret Coins

 * During the first ship sequence, avoid the obstacles and carefully go up above the spikes to collect the coin.
 * In the second ship, go through two gravity portals and carefully go through a 1 block wide spot to obtain the coin. Then go through a blue gravity portal and continue as normal.
 * The third coin is located under the mini-cube sequence. When you are shrunken, go up two staircase-like blocks, then get launched up and tap four times up on yellow rings. Instead of tapping four times, tap three times and let go, immediately hold again, then tap on the blue ring, then continue to the level.

Trivia

 * The first 43 seconds of the original Clutterfunk soundtrack is clipped, possibly due to level length, making Clutterfunk one of the only two levels not to begin as it begins in the full soundtrack. Polargeist is the only other level with audio cut from the beginning.
 * Along with Electroman Adventures, Clutterfunk also unlocks a ship when it is completed in normal mode.
 * Completing the level takes 1:39.
 * This is the first level to have the line change color. If you look carefully enough, you will see the line change to black in the first mini-cube section. It changes back to white in the first ship section.
 * At 12% it's possible to jump between the spike and wall and fall outside the level, making you crash; however, this requires great timing.
 * At 23% it's possible to jump over the gravity pad and spike and jump again to land on the ceiling of the next tunnel, though this requires timing.
