The Nightmare Realm

The Nightmare Realm is a demon level by AirSwipe created in 1.9, and updated with coins in 2.0.

Description
The Nightmare Realm was AirSwipe's first rated demon level. It seems to be inspired by Cataclysm.

Gameplay
The Nightmare Realm has very weird gameplay and some crucial timings. For an example, the first wave changes from mini to normal size quite frequently, and the last UFO has very precise timing.

User Coins

 * The first coin can be found in the first cube part, attached to a pillar hanging from the ceiling. You can get it by pressing the blue orb after the yellow orb in the normal gravity portal.
 * The second coin can be found at the wave part. At the mini wave spam, the coin is located far below the normal size portal. You can get it by simply going down at the end and quickly go up and enter the normal size portal.
 * The third coin is located at the ball part. After you get past the part where you roll over the spikes, simply fall down to the ground, as there is an invisible platform there. You can get the coin, and hit the yellow orb above you to enter the next part

Trivia

 * The Nightmare Realm was harder when it was first created, after some time, AirSwipe admitted that the level was not verified legit and nerfed the level to Easy/Medium demon difficulty. No copy of the original level has been found.
 * In 2.0, there was a sequel to The Nightmare Realm, simply called, Nightmare Realm II.
