"Hwaa! Hwaa! Hwaa! Hwaa!" -flaming skull projectile

The flying screaming flaming badass skulls fired by Nitrogolems have similar homing properties to missiles shot by DOOM's Revenants but with significantly less complex logic behind them.
They seek out a target inside a 10 degrees angle and if the angle towards the target is larger, they only adjust themselves slightly. This makes them easier to dodge than Revenant missiles and what causes them to visibly "forget" the target. While the target is within this threshold angle, they adjust their trajectory by 20 degrees towards it every 5 gametics (I am not sure if it is 5). This makes them more accurate seekers than Revenant missiles but overall less aggressive at pursuing.
I always had trouble making the projectiles orbit but it is indeed possible even if they break from it easier too.
