Geometry Dash Ominous is a Normal level rated 3 stars and 3 user coins created by Hyenada. With its distinctive layout and evocative soundtrack, this straightforward level has proven itself worthy of inclusion in the Shadow Gauntlet. The level's use of a black-and-white color scheme and well-selected music, a remix of the Lavender Town theme from the Pokémon Red and Blue games, contribute to its eerie mood. Pyramids and a candle are the level's two primary creative components, and there are also a number of other effects including wavy stripes and falling circles.
Ominous starts with a cube stage where players jump over poles and platforms while avoiding spikes. This is followed by a robot stage with similar tasks, jumping on pillars, platforms, and clicking on spheres.
The ship phase comes next, where players must navigate white walls interspersed with bricks. This section requires players to fly around obstacles in their path.
After the ship stage, there is a short cube stage, where players jump on platforms and over spikes. The next stage is a double-speed UFO, where players must navigate invisible walls that can throw them up if they land on them correctly. There are also decorated spikes on the floor and ceiling to avoid.
Following the UFO section is another cube stage where players must jump on pillars and platforms while avoiding spikes. There is then a short section with the ball mode, where players must change gravity to progress. The level ends with a short UFO section where players must jump over poles and saws.
The penultimate part of the level is a ship section where players must fly through small gaps with spikes. Finally, the level is completed with a robot stage, where players must pass the level.
