Jump on walls and evade a volcano's wrath!
A legend tells of an island of flightless birds.
Said birds are required to do a sacrifice. Each year, they throw one unlucky bird into the "Abyss" to spare the others from damnation.
It is told that a bird may climb out and break the island's curse.
This is not the story of the one who succeeds.
This is the story of the ones who fail.
