Highlights (spoilers):
The first character died trying to force the door after some poor intelligence rolls. The next took a few spears to the face trying to toss our dead hafling friend to trigger the trap, but rolling poorly and getting skewered.
I put the statue in a cage and gave it a bit more mobility to gather interest. It worked but I rolled poorly after the first two hit.
The snake garnered little interest, it got a surprise round and that was it.
The group almost attacked the crystal men, but a few great intelligence checks warranted letting them know they were peaceful.
They wouldnt drop the floor

They crushed all 7 skeletons, no clay generals, and they took enough crystals and took long enough that I ruled it leaked enough water to kill the soldiers (avoiding a TPK)
All in all, with 15 players, we completed it in 2 hrs (I rushed them), including char gen, and most seemed to enjoy it. Up to 30 entered, 8 or so survived.
