Cuphead: Aviary Action is a fan-made browser tribute to Cuphead: a 1930s-cartoon boss fight against Wally Warbles, with the parry and the phases the original is known for.
Aviary Action is a fan-made browser game in the style of Cuphead, built around the bird-boss fight: a cartoon aeroplane, a huge feathered opponent with phases, and pink projectiles that can be parried with a well-timed jump to charge the super meter. It is not the Steam game and does not pretend to be; it is one fight, drawn and tuned like the real thing, with Simple, Regular and Expert difficulties.
It shares more with the Sans fight than it looks: the attacks are fixed, the safe answers are learnable, and the parry is a blue bone in reverse, a moment where doing something is right.
No. It is a fan tribute built around one boss fight. Cuphead belongs to Studio MDHR.
This version is single-player.
Because the attack is the same every time. That is the good news: learn it once.
