Thank you, I appreciate that :D For the Line of sight, I thought some time if I should do it, but it would have complicated things so I decided that this would be something to work on if I had spare time in the end. I didn't so I am thinking about doing it for a future release.
In the first room you need to move, because to get the range-spells, you need to pick up the book first. It is a bit misleading though. I am also thinking for a LoS check for the ghosts which gets deactivated on distraction, but I am not sure this is the right thing to do. Thanks for playing!
