Thanks for playing! Yeah the floor height needs to be set correctly on your quest otherwise you will have trouble grabbing the objects on the floor. I think in the future adding an option to reorient the seat height regardless if your floor height is set correctly or not could be a solution. I played the game so many times during development I can get all the keys in under 20 seconds. I wanted to add some more VO where he says stuff like, "Maybe I should use these bones to knock the keys free" or something like that. As well as something to tell the player to stand up and climb the chain to get out.
Femur for the win!
