found second angel in secret room back home... double jump doesnt reach high enough to get back out, so needs either platform in the entrance 'pit' or a busstop in the room.
Ah! That's a good catch I hadn't thought about getting stuck in there - It's an easy fix to make though, thanks for letting me know
After you find angel statue 3, its not added to the fast travel options
Also when you are in the lock pick menu, you can open more of them in the background
That's an interesting one I'll look into that
