I like the idea of an adventure set in an abandonned space ship, though there's some of the backstory of said ship that I had trouble understanding, at it seems it's crew was human but it isn't really explain who are those humans and where they came from.

I also felt there seem to lack a conclusion to this "dungeon". It doesn't necessarily needs one, so maybe that's a me issue. Or maybe I wasn't super attentive when I read the hook, but if I remember correctly, the party just "happens" to find the spaceship, they were not sent there by someone or for a specific reason.

I don't intend to run this adventure, so I didn't bother much to try and understand the key system and other space item and transporter that helped go to deeper level. I did enjoy how there's a whole ecosystem inside the ship. I also like the "in-between" level where the party could explore more mechanical spaces and such. I do wish there was a little more stuff on those level though.

Made me want to go check how mindflayer evolved from 1E + gave me a better understanding of vegepygmy, which is neat.
