You’re a bird, one of the final inhabitants in a world of catastrophe.
The objective is to navigate through the post-apocalyptic ruins of former civilizations and search for survivors.
Where there used to be ground, grassy fields, high mountains has since become a bottomless pit. You’re going to have to hop in between the remains of once great monuments.
Since the cataclysm, gravity has become significantly stronger and will pull down even the most mobile of birds, so you need to coordinate how high you go so you can land in the right spot.
Otherwise, you join your fallen bird brethren into the abyss.
I suppose it’s in your blood to experience extinction. Your dinosaur ancestors were wiped out by a meteor millions of years ago, and as a bird you are a remnant of that legacy. But this time you have your own battles to fight.
