Room can be effectively skipped if the line is changed to:
"if (!bm[1] && num == 12)"
Taken that from the first room code, it skips tutorial messages from Chest area you go to the next floor and then it plays as usual.
I can check old versions to see if this line worked properly.
PS: Yeah, I checked EA 0.4 v2 and apparently he messed up the code after that line. Should look like this to
work properly avoid softlock:
