'kay I noticed in one of the ghost houses, there's that moving hole in the floor (used only in Chocolate Ghost House in the original).I got that bug too AND later the ghosts disappeared too!!! Anyway I've played thru the game now, I enjoyed every single piece of it. I hope to see more hacks by you, RAGB!!!
Except sometimes the hole disappears (especially if I see it, leave and come back), and the floor LOOKS solid, but it's not.
(though this might have been a bug with the original game)
