It is a 10-star Extreme Demon level made by Lithifusion that BoldStep validated and released. Most of the level is memory-based, with a few fake objects and orbs with invisible spikes on top. For the "Viral" motif, it uses a red color scheme, while for the "Regular" motif, it uses a green color scheme. After its first release, it remained unrated for some time until being given a rating more than a month later.
