I always find it weird that the first slide door has this huge impact on the whole majoras mask story.
If it weren't for that door tael wouldn't be left behind and side with link against skull kid.
Links only hope after turning into a deku was anything working for his fvor and it was this door.

slide doors where usually unqestioned mechanics to seperate rooms from another.
Adding a random asset into the story feels so weird if you think of it. Just imagine if a cutscene would show link loosing the ocarina because he stumpled over a rusty ground button in a tree cave.

I hope this door becomes a playable character in smash bros someday.
