I've run one session of this so far (using Brighter Worlds, a Cairn/Into the Odd hack). My impressions so far: This is perhaps my favorite OSR module that I have run yet, besting Winter's Daughter.
What makes it so great is the automata. They give the PCs something to "do" besides fight monsters. They can fight them, study them, and re-program them to their own ends using "command slips" that can be found scattered throughout the temple. The automata serve as puzzle, monster, and asset. I think the players had a huge sense of shared accomplishment when they first got a hulking "Tarantuton" working on their side.
We got just up to the point of entering the hornet's nest. I'm glad they didn't get much further because I feel like the motivations of the NPCs here could use more fleshing out. It's nice that there are two factions of hornets, but I'm not entirely sure how to play the characters. I'm gonna have to do some work on my own on that. Similarly, there's a sentient automata the PCs can find called "The Bookworm." I wish there was a bit more about its motivations, its wants and doesn't wants.
Those aren't huge gripes though, given how good the module is overall. I'm looking forward to finishing it up.
