Mechanics
What Halo of Flies does
- Two protective flies circle Isaac after pickup.
- Their orbit can intercept projectiles and they can damage enemies that touch them.
In a run
Practical note
Face a stream of shots with a fly between Isaac and the shooter, while keeping room to dodge anything that slips through.
