Hmmm, is it a secret related to what name you put in? If so, is the name refered somewhere in the game?

Yes indeed! It takes a certain name to visit the VIP Room, and as I mentioned, you will know right away if you got it right when the chord and music start playing. IIRC you also get a special line from the old man, but it can be hard to notice because it's not something loud like "YOU DID IT".
For those looking for more, MinoAnon posted about the origins of Minotaur Hotel from 4chan (which is explored a bit in the VIP Room) in a tweet here. It might just help. ;)
Alright, MinoAnon tweeted out that the password for the VIP room is fair game! For anyone who has not found it yet, the name you must give your character for the run is... Anon! If itch.io supported rollover spoiler text, I'd've put it in the first post, but instead I was just subtly-unsubtly italicizing it in my posts, haha.
