Like how you can steer StarFox's ship by turning the 3DS. Do you think X/Y will make use of that feature like perhaps tilting your 3DS sideways at the moment an enemy is attacking will increase your evasiveness somewhat? Or tilting forward when you attack will increase the damamge slightly
Apparently Inkay evolves when you hold the 3DS upside down when he levels up --- "There's no point having the biggest and most explosive gun operated by someone who can only use a slingshot. That's what the Vita is"
