In two words: Hauntingly beautiful. From music to art to writing to UI, each piece (petal? >:) ) of Burdock comes together in seamless unison, supported by the effectively used atmosphere of flora, creeping mists, and fall. And, of course, Fae.
The description of the wedding at the beginning is immaculate; I've never read a more harrowing instance of "I do." The voice of the protagonist (who is gender neutral and can be renamed) has that lovely, time-appropriate charm of being remarkably well-spoken and logical, even when their means are meager.
As for the primary love interest, The Fairy... Woof!!! How could you NOT fall for them after they offer to /bargain with Death/ on your behalf?! (Sure they called us a "Sacrifice" and mentioned how delicious you must be and want to squirrel away your name in exchange, but we all have our quirks don't we)
In addition to a solid writing and gorgeous artwork, there are in-game riddles and puzzles that are both clever and wonderfully implemented - though, admittedly, I had the privilege of early access to the story and was not able to try them for myself without getting spoiled.
Every single character was memorable and delightful to meet.
The title card graphics are a particular favorite of mine, and the sound design is incredible as well -- special shout-out to the sorry steed and all the other animals I love so dearly.
A wonderful, wonderful game overall.
