You start with a ship that, perhaps, has already ran out of space, but then you need to load in more things (probably some refugees?), and need to choose what to get rid of and try to continue surviving.

Gameplay will alternate between "inventory management" (choosing what to get rid of to replace with your precious cargo), and encounters where you toggle power levels to a bunch of different sub-systems. I think this will work, if I can complete it in time =).
