Pulsar is a 2.1 Insane Demon collaboration created by Akari and Zhander and verified by Zhander. It is a difficult remake of Nine Circles.


The level starts off with a 4x auto section, which then transitions immediately to a timing part. This part looks like it is closely related to Danzmen's style. The player then has to endure a ship part. Then it goes on to a spamming ball part, like Sonic Wave. It goes on to another auto part, showing the Pulsar logo. Then it goes to the infamous Nine Circle Wave. The wave tells the player that they have to spam, memorize different patterns and that it has a few fakes. It goes to a cube part with a dash orb and one jump. It finally goes to the last cube, you have to only time. Then it shows a Jolteon picture, and the level comes to an end.


  • The password for the level is 167428.
  • The Pokémon in the level is a Jolteon as Akari likes Jolteons.
  • This is one of the Nine Circles levels named after a Celestial Object and the suffix "sar".
    • The other one is Quasar.
      • Both have Mafia Pineapple songs, a unique design for a Nine Circles Level and the songs (Genesis and The Cosmos) were used in different levels (like -Sirius- + CholeriX and Cosmic Calamity + Galaxy Breaker + Fractured Galaxy).
  • According to Sea, this is the best rated Nine Circles level, this level is tied with Poltergeist Reborn, but that level is unrated.
    • JakeM2436 said this is a very fun Nine Circles Level.
    • This is one of the most liked Insane Demons and Epic Demons in Geometry Dash.
  • This is one of the hardest demons not in the Demon List (includes the legacy list).
    • This is also one of the hardest Nine Circle Levels.
  • This is one of three epic Nine Circles Levels.
    • The other ones are Nine CircleX and Nine Paws.
      • All of them are Insane Demons and have a similar difficulty except Nine Paws, which is easier.
