Use it like a real elevator. There somehow has been a bug fix with this where the motor sound will no longer play if the elevator is on the same floor as is pressed. I have no idea how that happened. :P (Now I do, it's to do with variable timing. :P) This is my most advanced simulator yet, with shaft doors and a grey rectangle for the interfloor for the first time! The gap between the inner doors is so you can see that.
