Electrodynamix

Electrodynamix is the fifteenth level of Geometry Dash and the fifth level to be rated "Insane" as of Update 2.0.

Description
This level starts with a few simple jumps with jump rings, then becomes considerably harder with faster speed, flashing colors and invisible spikes.

Update 1.7 introduces the speed portals, but only two are shown on the level: the double speed (green) and the triple speed (pink). You start the level with normal speed, then the double speed starts early in the level. When reaching around 60%, the triple speed is triggered at the beginning of a ship section, making it significantly harder.

This level has some new features as well. The colors of the background on the first ship and UFO paths are the same as the player's primary and secondary colors. Bright colors make the UFO path very hard since the spikes are hard to be seen, so it is advised to use dark colors.

The hardest parts of this level are considered to be the ship segments during triple speed and mini mode, after around 70%. It generally takes lots of tries to handle the control of the ship while passing narrow paths, even on practice mode.

Secret Coins

 * At the mini UFO, dodge through two saws that shield the secret coin (tapping to the music helps). An alternate way to get it is to go under the saws and press 3 or 4 times to get it. However, the former method is the best because the latter method is very risky and more difficult to do.
 * After the double speed ball section, tap two blue rings, but avoid tapping on the yellow one after them. Jump to get the secret coin and return to the normal path, but time it carefully or you will hit the line of blocks above you.
 * After the mini ball section, jump on the purple and yellow jump ring and not the blue one. Then immediately focus on the ground and jump right at the end on the blue gravity pad to get the secret coin, then jump again to keep going. Correct timing and practice is required.

Trivia

 * Electrodynamix is the first level without a secret coin in a ship segment, despite the level being infamous for its ship segments. The second level without a secret coin in a ship segment is Deadlocked, but to get one of the coins, you must get a key in a ship segment.
 * Electrodynamix introduces the upside-down UFO.
 * Electrodynamix is the first level to introduce colored blocks and spikes.
 * Even though Update 1.7 also introduced the orange and blue speed portals, they are not seen in this level. They are not used in an official level until Hexagon Force.
 * Electrodynamix is the last known level to contain the classic thorns, which are during the mini UFO sequence.
 * Besides the speed portal mechanic being introduced in this level, this level also introduces the custom-colour level mechanic, in which the background color is the same as the player's colors (mostly notable on the first ship path and the UFO path).
 * It takes 1:22 to complete this level, making it the shortest in the game, along with Cycles.
 * Due to the faster speeds present which lengthened the level, Electrodynamix is the only official level where it is possible to crash at 99% by hitting the last spike. This used to be the requirement to unlock the "So Close" achievement until in Update 1.9, where the percentage was decreased to 95%.
 * It is also the only official level where you can crash at 0%!
 * Electrodynamix is arguably more difficult than Theory of Everything and Hexagon Force, though they all reward the same number of stars. This is generally because of the flashing colors and the fast ship parts. This is also why many people think this level should be rated demon.
 * Electrodynamix is the first level to feature a triple speed portal, the second being Deadlocked.
 * Electrodynamix is also the only level where you can collect a secret coin while in triple speed mode.
 * The background flashes in the first ship sequence and UFO sequence is depending on the player's color 1 and color 2.
 * This is the only level to end in triple speed mode.
 * At 2%, there is a missing wavy thorn spike.
