Behaviour[]
When this enemy enters the stage, it will travel in a straight line in a random direction, and will reflect off any solid surface it comes into contact with.
When the player shoots this enemy, it will separate into its purple and yellow constituents: the former are known as tracking darts[1], and will pursue the player at high speed and with a wide turning circle; while the latter are known as blockers[1], and will hover slowly near where the enemy separated.
Trivia[]
