The game we are playing as it is now, is an on going full overhaul, that's why it's a mess. As Mr. Height mentions check for older version. The older versions had 5-6 parts with a solid plot that made sense, the dev decided to do it over and is adding in parts from way smaller versions( early versions had single floors with many rooms you could complete in about 10-20 minutes). Redoing all of the artwork and redoing the code. As for part 1(the spaceship) I've played it so many times, I skip straight to part 2(the house). That being said in older versions before the overhaul, you had to play part 1, there wasn't an option to skip, the escape pod was the fast route home, or you infest the entire ship to get home( incentive for infecting the rest of the station).
