First off, this is great design. The colors work well. I love the map and the asteroid as a text box. What did you use to make the map?
The concept is fantastic. I love the boring 9-5 nature of it. The world-building is excellent and well thought out. Are the character nicknames their call signs?
Really good hooks, guidance, and thought-provoking ideas for continuation.
I liked the sudden and classic body horror. Keep players on their toes.
The major and minor malfunction tables work well. Lots of good ideas for complications. Does the Lighting failure major malfunction mean that the only lighting comes from the hatch markers?
I like the map, but I feel like the map and the room descriptions, while perfectly functional, descriptive, and well-done, could focus more on interactivity, provide options to more clearly serve the gameplay, or be more flavorful. I can see the explanations of the spaces not figuring into the session much.
I think this is really solid and well designed.
