Circlicide

Overview
A unique type of spermicide that rotates at a constant speed instead of moving along a line like most other types. This can lead to the player getting trapped within their circle, requiring them to time their escape in order to avoid getting hit. They have notable segments in Stages 2 and 4, demonstrating their presence within the levels as being more akin to an obstacle than the average spermicide.

Hard Mode
Circlicide appears much more frequently in this mode, where they are mashed with other types of Spermicide to give the player an even greater challenge, compared to a standard playthrough where they are often delegated to their own sections.
