Your bird shoots by itself. Your only job is to stay alive in the storm.
One hit from a fireball or a demon ends the run. Only the small pink dot in the middle of the bird counts.

A boss wakes every 45 seconds or so. Its patterns change as it fights.

Staying alive: +10 a second.
POWER-UPS
Blue: spread shot for 12 seconds. Green: a shield that takes one hit. Gold: a bomb that wipes every fireball off the screen (B, right-click, a second finger, or B on a controller).
