Geometry Dash Firewall is an Insane Demon level rated 10 stars, created and published by Hinds. It is well-known for its brightly colorful decorations and flashing lights. This level is considered challenging because of its famed wave portions and numerous critical timings. The song begins offset from where it ends in Fractured Circles.
The waves' highly confined places, triple speed, and vital timing are significant features of the Firewall, as are the ships' large straight flying and the balls' massive crucial timing, while the cube sections are much easier. When the music slows down, the level becomes easier, with a final cube part that mirrors the final cube section of Breakthrough; however, the player must be cautious of quintuple spikes in triple speed toward the finish of the level. Because of the large number of triple spikes, the first sequence was dubbed "The Paradise of Michigun" by some. A remake of Firewall dubbed "Mussum" was recently produced and featured.
