Thanks for playing and the feedback. I was going for creepy.
On the controls front: When I have been testing, I found the best thing to do is to get into a good position in a room with witches, before they start throwing curses, then stay put while typing the counter-curses, then move around again when all the witches have expired. For example, dive through the door then back off into the nearest corner, then stop moving and use both hands to type the counter-curses. It helps if you can touch-type...
Also, make sure you get all the potions that the witches drop, as you can't go back and collect them later (the room won't be there).
