Savoir-Faire is, first and foremost, a difficult game. What kept me going was the mystery, the atmosphere, the incredibly versatile and unique magic system, and the desire to finally get something good to eat.
In this game, you get to "link" two similar objects together depending on their properties. Then, what you do to one item will affect the other. Sometimes, you'll have to modify or change items so they can be linked up to another. Reverse-linking has the opposite effect, applying one item's properties to another. This also leads to a bunch of fun Easter eggs. When I first played, I underestimated the system, so a bit of advice for new players: Don't be afraid to try everything. Sometimes a solution will work when you don't think you can do it.
The game's atmosphere is notable, too. You're alone in a fancy mansion, exploring every nook and cranny to piece together what happened to you and Marie. It genuinely made me gasp at some of the plot developments or more unexpected things I came across: I had no idea (Spoiler - click to show)Marie was alive! The bits of backstory you come across are meaningful and communicate just how intense it can be to live in a world with this kind of magic.
The cooking puzzle deserves special mention. This thing drives the game: I loved finding new ingredients in order to finally cook these recipes that had been taunting me for hours. It's rewarding to use, and allows you to segment your goals a bit more: what do you have, what do you need, and where do you think you can get it?
This game is an absolute classic. Give it a try.
