Jack stuck in Mt. Peril Hard

[otg]

Another possible JS in this mansion is in the same part as the screenshot from spacegorilla. I just played it and opened one of the purple doors in 15301, and the purple in 14903. I also used my green key from 15101 in room 15102. Therefore I could not get the purple key in 14901. Don't know if I missed something though, but I really couldn't see a way out so I had to restart from last save and open both purple in 15301. That worked fine.
