Hey there, thanks a lot for your awesome feedback - glad you enjoy the game!
Including controls and options in the pause menu is definitely on my list for the future. The character's eyes not closing was a bug, and the number of characters that can exist on the map simultaneously is unfortunately limited due to performance reasons, so at the moment I can't leave them there forever without negatively impacting the game performance.
A gravity gun would indeed be a cool addition, perhaps something to consider for the future :)
