The art is so great and I think my personal favorite of the jam. I also have a deep love of bugs and praying mantises in particular as well as obelisks, ancient lost civilizations and some of the other tropes you've used. Given that there are these familiar elements, I think it could have felt stale, but the art, the added dice mechanic, the solid writing and the easy playability all really elevate this adventure. There was an Brenan Lee Mulligan quote about how execution is everything and you really did a great job executing this one shot.
I do think the Deactivation and Destroying the Obelisk (normally) endings could be punched up a bit. For example, even if they briefly see the Star Presence, that should come with a greater consequence than a stress point and panic role, in my opinion.
Great job! If I play it with my group I will send you a note on how it goes.
