Thank you for your exceptionally detailed feedback.
Perhaps you are the first one who wrote about the toilet. During the first playtest phase, there was no option to pee, and without it, there was no fun on the ship. Because of this, most of the playtesters committed suicide. I played with the idea a bit to leave it that way, but it might have been a bit harsh for the late-night news: "Massacre in the GameDev.tv Game Jam!"
Items and storage:
I think you did well. Maybe there's another, better logic to store those items; I think the real problem is the limitation of the inventory, especially if you are sloppy and don't have a perfect memory.
Were you able to complete Day 2 with a specific outcome?
