After reading mother's letter on the wharf, Louis says "language", but there's a typo in the subtitles - 'langage'.

By the way, I'm a professional game localization specialist and I really like your game. If you need my service in the future, I'm eager to collaborate.

Here's a typo in Russian subtitles. It's the ending, where you decide to follow Adams, but quit on her before getting drunk.

It should be "я решил", not "мне решил".

It changes a lot. It can lock or unlock a lot of content, really tailoring the story based on your choices.

I suppose, it leaves room for a sequel with Louis's new adventures. Although there are several other daemons mentioned in the game. The child stolen from Venice and other Louis's siblings, including Augustus mentioned in the end. Emily and Emma, even Elizabeth, if she survives the island. The sequel can take place even in another history period due to daemons' longevity.
