Aside from getting the monster models, the module itself looks fun. The first half is a fairly straightforward fight, but the second half is a puzzle for the players to solve. I also like the fact that the puzzle is actually a trap - one of those times where it may have been better overall to have left everything alone (a tiny bit like Tomb of Horrors, but not nearly as deadly).
There aren't really any continuing hooks at the end.
<END SPOILER WARNING>
So a nice adventure to throw in when you need something to fill a session or two between the actual plot points.
Of course, this was written under OGL 1.0 - so for anyone interested in that bit of fun.
Because it is all fun and games . . .
