I am totally frustrated by the explosion on the first lvl where you have to shift! Is this game broken? I see code in the upper left after the explosion.
Oh, and it is far more likely for a girl to have a gender identity crisis (tom-boy anyone?) before puberty than a boy would be dressing like a girl (curls in hair, etc) before puberty
LOL - Popo is a girl.
She has large eyes - estrogen! Part of the clues is that her name is Popo - The Younger.
I'd say Popo was say, 11 years old and about to hit puberty. Also, she has ring curls under that pig helm, and what looks like a slightly smaller waist than hips...
... and yes, girls 'play' with sling-shots
