Geometry Dash Classic is an Insane Demon level rated 10 stars with 3 user coins created by ComplexX. It is often recognized as one of the more difficult remakes of Insane Demon Nine Circles. This is one of the very first Nine Circles remakes. Unlike other Nine Circles levels, this one has a green color scheme and, for the first time, does not have a ship sequence or a ball portion. This level focuses on timing and memory skills in particular. Its difficulty is comparable to that of Headrush and Sharp Minor, the former being a Hard Demon and the latter an Insane Demon.
