I love the design where the dice form actual physical representations of the obelisk, that's so creative. The art is amazing too. So far, I don't have much to suggest; it's very cleanly written and contains just enough info to be both very pick-up-and-play and versatile. Always a fan of some good eldritch horrors from the stars.
As earlier comments have pointed out, this is a little more dice-driven, and the overall story structure is pretty clear. Personally, I don't think it's a problem, though. This module would work very well for players coming from Call of Cthulhu or video games (both of which I work with a lot). It provides suspense, flavor, interactivity and versatility, so imo this can likely become a good intro module. The dice balance system is a very creative design, though I can't tell how well it will work in-game. If I ever run this, I'll make a note to come back and leave a comment.
All in all this is a fantastic module, and I must stress how much I love the art. ty for the game!
