I've been taking a break from replying to people because I've been in kind of a bad place but I'm genuinely shocked you found that.
There was another ghost in an earlier version of the game that shouldn't be available on itch.io any longer. She had rng to appear and I set the odds to something really low like 1 in 999 plays.
I edited that ghost out in later versions but I kept a dummied out form that shouldn't be able to actually appear in game just to avoid breaking the ending system.
I originally intended five different endings and an extra area but they changed the tone of the game too much.
I decided it was better to keep the experience of the game as it was because it meant something to people and I didn't want to ruin that.
