Poltergeist

Poltergeist is an insanely difficult demon level by Andromeda. Even though it is rated demon, it goes far beyond a demon's difficulty, hence termed an "insane demon".

Description
Poltergeist is often considered the 2nd, 3rd, or 4th hardest Nine Circles remake, standing behind Crimson Clutter, Antique Circles, and Down Bass (excluding the debated Sonic Wave). The level has notoriously random timing in the first half combined with tight spaces and very awkward movements, but dramatically loses its difficulty in the second half.

Gameplay
The level starts with a simple cube with a few simple jumps and tricks. This is followed by a ball and another cube sequence which are both very easy. The player then reaches two spikes, signalling the beat is about to drop. When the beat drops, the player goes into one of the most notorious waves in the game, now with many awkward timings, tight spaces, and triple speed pretty much throughout the entire two wave segments. The first segment is all about timing and very tight spaces, along with a triple speed rocket that requires some pretty good straight flying skill. If the player makes it past the wave, they will enter a cube sequence saying "TAKE A BREAK". This part has 5 sets of double spikes that the player must jump over in half speed. If the player makes it past, they will go back to the wave, albeit easier than the first segment of the wave. This area has much larger spaces and has a pretty forgiving first half, but has a very troll-like ending, with a mini wave at triple speed and then through a tight space and bugged area in single speed. If the player makes it past, they will see a giant "GG", and must hit two last jump rings to beat the level. The text "ANDRO" can be seen at the end.

Errors

 * It is possible to skip the half speed at 60%. If the player manages to do this, the player will crash into one of the double spikes.
 * At 92%, it is possible to skip the invisible spikes, and the player will be sent to one of the spikes.

Trivia

 * This level is considered to be one of the hardest Nine Circles remakes.
 * Due to it being so hard, Andromeda had to hack to verify it.
 * It's the level with the highest difference of difficulty between the beginning and the wave part. In fact, despite its insanely hard wave, is also the level with the easiest beginning.

Fails

 * SuperPizzaLuigi crashed at the beginning of the last cube twice due to a bug above, and gave up on the level due to it.
