-When the bullets are far, mentally project their direction in relation to where your hitbox should be
-When the bullets are close, don't look at them, look out for gaps instead
-Have a vague awareness of where your hitbox is at any given time (only look at it when micrododging is unavoidable)
-Avoid bottom hugging, it restrict the space you can move around and forces risky dodges upwards when cornered
-Familiarize yourself with alternating between focused and unfocused movement : slow down when there is a bullet somewhere in the direction you dodge to ; accelerate when you aim for a gap
-Prioritize positionning yourself in the 4 cardinal direction in relation to gaps between bullets (diagonal dodges should be last resort)
-Better time out bosses than die to bosses
-Better lose bombs than lives
-Don't chase for ressources or point of collection when there are bullets on the way
