Thank you I'm sorry though, it isn't to do with the end of the game. I do appreciate you taking time to give working though, and good reasoning, but not the direction I'm coming from.

Okay I'll give some hints:

Firstly, most of the lines are pretty literal, or at least cryptically refer to specific things. As I said, there isn't much filler, pretty much everything is pointing towards something.

Secondly, the last four lines are intentionally distinct from the others, as is the title.

Okay, I'll give two bits of information that have been correct so far. The father and daughter are Godo and Yuffie, and the spaceship does refer to Rocket Town. There might have been more, but I'm too tired to check coherently just now.
