My dude, there are mad challenges you can come up with in a PF game. Here are a few of my faves:
-Oozes are hella rad for a key trap. There's a key on the ground, but it's all up in a clear ooze (custom-made mini Gelatinous Cubes for me), and that can open a can of whoop-ass on players who don't keep some eyes on the suspicious key on the floor first.
-The party enters a freaky room with a bunch of statues creeping at them with their scary-ass gem eyes. The statues all hold down a pressure plate, which triggers an arrow trap from one of the walls if the statue gets budged even an inch. The thing is, all the statues need to be rotated clockwise to open the door to the next room, and trying to push them normally triggers an alarm.
-This isn't quite a trap or puzzle, but it's cool anyways. Have a bunch of scary dungeon things trying to kill your peeps for five or so rooms, then throw something cute at them. Not "Killer Rabbit" cute, though. My dude, you want a completely harmless, mundane room in the middle of a deathtrap. Maybe the vampire who owns this crib likes pink, fluffy things and kitten posters. I pulled this on a few of my guys, and they spent half the session looking for traps or monsters. They dipped out of the dungeon after just seeing that room... It's wicked how soon adventurers freak when nothing's trying to kill them. ADDED FUN- Roll a few dice and laugh every once in a while.
