Every time I do one of these jams, my "todo" list that accompanies the game as it's being made becomes soooo long. One of the items on the todo list was a player power up that could appear that would be called something like "silent keys" and it would make it so that monsters behind locked rooms wouldn't wake when the key was picked up, but rather only when the lock was finally sprung. Sadly, there was so much to do I never got around to adding it (I was still trying to balance the blue "dodging" ghosts up until the very last minute). Thanks for the feedback!
