Extreme Chaos

Extreme Chaos is a demon level by Nether. It is known for tight spaces, heavy memory, hard timings, and unintuitive gameplay. It is generally considered an Insane Demon or a Very Hard Demon.

Gameplay
The level starts with a cube part with some timings but mostly memorization. Then there is a similar ball part. This is followed by a rather tricky dual mini cube. Then an auto dual ship is followed by a very difficult mixed dual of ball and UFO. Then a relatively easy ship is followed by a long cube part that starts off easy and then gets very difficult with hard timings and lots of memorization. It will pass through a dual portal as well as some mirror portals. This cube part can be compared to Doomsday II. Eventually, there is a moderately difficult ship part with some invisible portals and moderately tight spaces. Then a short ball part with a little memorization is followed up by a cube part with a bunch of memorization and a few timings. Then there is a dual cube part that is mostly easy. Then an auto ship leads into a rather difficult dual ship part, with the last stretch looking like Hexagon Force. Then there is a very tight ship part, followed by a mini cube with some tricks. There will be a series of mirror portals with a hidden blue orb. The player must tap that orb, and then spam click with the UFO portal it leads to, in order to avoid dying at 98%.

Trivia

 * This level is very buggy and is likely hacked.
 * The part at 14% may seem impossible but actually isn't, due to a near impossible to see orb.
