You need to have solved Nell's small secret, and you need to have heard Samarra's story of how she adopted Nell. Both of those things generate a clue that shows up in the clue interface with a headshot of Nell as the icon.
The music is licensed for use in the game only. I don't have the rights to distribute these tracks individually or as an album. If you wish to search for the tracks online, you can find their names and composers in the in-game gallery.
As I said, I don't have the license to distribute these files. Instructing you on how to potentially extract them would be a breach of the license in itself.
What would be the purpose of updating the game engine? I'm using a newer version for my new game Supermodel, but I don't see any reason to update it for LLtP. The gains for the players would be minimal at best, and the risk of bugs and unintended function changes is severe.
No. The reasons why saves are incompatible won't change with the passing of time. You're either going to have to stick with the old version or start over. You *could* manually copy your saves, but you are likely to break something (which is why I made the saves incompatible, to begin with).
Technically more, because you have the option of having Belle also come with you during each ending.
