Journey and Shadow of the Colossus. Deffo interested in this.

I need some help if no one minds! Basically what happens is the game runs perfectly smoothe and fine until the part when she unlocks the orange balls and has to make a circle. There I can make as many circles as my little heart desires but nothing happens. I was sure it might just be my computer, but I have plenty of storage space and a reletively good and fast working graphics card, so that was unlikely. It's probably more likely to be a bug in game that should be fixed by my amatuer assumption. If anyone...

So I notice I plaid the boy first and the boy had red clothes and a reddish colored dragon. And at the end of the game the Girl that appeared had blue clothes and a blue dragon. Coincidence? So when I started new game + I chose the girl instead of the boy but still got the red draggon... So Is there a way to change the dragons color too or are you just stuck with the red dragon boy or girl?...

Gotta be honest, I've spend 5 minutes with each titan in the mirror world, I chilled on their backs in the cloud world for 5 minutes each while calling them and everything. I really don't understand how you're supposed to get that achievement... -_-

My understanding was you could choose between playing a girl or boy in this game, but it stuck me with playing the girl. How do you change to the boy?
