Good stuff!
"Random mysterious thing that drives most of the crew insane except the player characters" is a well-worn trope, but it does what it needs to. The Melded are my favorite part, without a doubt. That's a clever mechanic for determining HP, and the name and visuals are good. The NPC tiers seem like a design artifact from an early draft, and could probably be cut. I'd recommend swapping the stars with various numbers of points for alternate shapes for black and white printing friendliness. There is a lot of purple prose taking up space that could be better utilized, which seems to be a common theme across the submissions to this jam, but they add some nice flavor, so they get a pass here. The art and layout are good, but I can see this turning into a confused maze. The whole thing is basically "navigate a bunch of enemies to get the doors open to kill the captain and use his keycard" and I'm not really seeing the "Survive, Solve, Save" elements and this reads like a prose-heavy DOOM level more than I think it needs to. Overall, it's a fun little dungeon crawl, but I think it's missing that special something that makes it memorable. Final note, the setup does not account for players who already exist, and a quick note that any personal belongings or weapons are stored in the crew quarters or armory fixes this.
