My favourite was Pic3, those two girls.. but I think there is something wrong with the questions as their eye colours are different, blue on top and purple below.
In Pic4, I don't see any bunny ears either! Unless that refers to the hairstyle to which I have no idea. Although this game was harder, I don't really see anymore rewards than the 1st one, which had more pictures and a better movie.
I think the pictures used were better than the 1st movie though. Although where are the hidden bonuses mentioned?
Lastly, the question are exceedingly devious! Especially the one about the maid regarding the rope.
You're on my favourite arthour's list now, lolz..
