Thank you for your comment !
Actualy the theme "behind me" , we adapted it like this : you are pursued by a monster behind you and to switch character you have to turn your head beceause the other character is a face behind you head
And for the glasse special object, it is used by the lights emited by Stein who wear glasses
But with what you saied i am thinking that we may be haven't been clear enough to show how our game is adapted to theme and the special object sso thanking to having pointing this out
