After sitting on it a few days, my opinion is that Threefold Recital is really, really good. If you like adventure games--like Ace Attorney, 13 Sentinels, or King's Quest--you should play it. I know there's furries on the cover art, but you don't need to be a furry; just go in blind.
The Ace Attorney games are its most obvious inspiration; the game is divided up into several chapters that each have a mostly self-contained story, and each one is good at building up a mystery and then throwing wild twist at you at the end. In the end, they all tie together and finish everything neatly. The writing is clever and made me genuinely laugh out loud several times, and there are several really great plot twists that I didn't see coming. I was worried that, being an indie Chinese game, the English translation would be really rough, but for the most part it's actually very good; you can tell the writer was a huge fan of Ace Attorney and was trying to mimic its style of wordplay and sense of humor (especially the name puns). I noticed a handful of grammatical errors, which particularly stick out because otherwise the text is very well-written, but they never got in the way of understanding what's going on.
One thing I think this game actually does better than Ace Attorney is the variety of gameplay mechanics; each one of the three main characters has a unique ability they use when solving their mysteries, and at first I was worried they'd be overused and would get repetitive, but nearly every time you use them, the game throws some unique mechanics at you and uses them in new ways. It never gets old, and the game has a few really clever puzzles, but it also helpfully gives you the option to skip the harder puzzles if you have trouble with them.
If I were to have one serious criticism of it... I feel like the story comes close to saying something profound about the nature of life, art, and memories. You can tell the creators put a lot of thought into it, and it'll make you think about it, too; but the game never quite comes out and states its thesis. It holds its punch in the end just a little bit, maybe because it assumes you'll figure it out on your own; but it definitely does have something to say about all of those things.
And a very, very minor complaint is that the cast of characters is almost exclusively male. I mean, it doesn't really matter because gender and romance aren't really important to the story, it's just weird that out of a cast of a few dozen characters, there's only a couple of women. Well, the guys are cute, at least.
The soundtrack is really good, too. I'm probably going to have it on in the background for a while. Play it!
