I'll see about it!
i had an idea while i was grinding away my skills, maybe idk... could add a sound effect.
for doors you could add in the sound of the door closing behind you and for stairs could add the sound of food steps for the delay.
it would improve atmosphere and also usability of the transportation mediums.
just an idea of course XD, i'm not at all familiar with your specific code so i'm not sure what can or cannot be accomplished.
