After Baldur's Gate and Yakuzas and Dogmas of Dragons I wanted to play some weird short game and D is a game of which I've seen a Let's Play way back when, but I didn't remember it at all.
There's a reason for it: it's kinda bad.

D is a fully CGI point-and-click horror game in which you come to your mad father who took hostages and end up in his mind palace solving puzzles and slowly walking around. The game is very cinematic and I'd even say looks and sounds good if very dated, but its gameplay is nonexistent. Due to likely high costs of rendering everything the game is really short, featuring maybe 15-20 rooms at most and only few puzzles of which maybe two or three aren't "you saw a color or a number or a pattern, remember it and input it".

The biggest flaw of D is that it really likes to waste your time by design. You see, you can't save in D. You can't pause. The clock is ticking all the time and after 2 hours you will die. Apparently developers realized that it takes like half an hour to beat this game after implementing the time limit, so towards the end of the game you'll encounter the Rotating Room. The contraption is slowly activated and after a short animation rotates the room in which you are standing so that the door leads out into a random location. Now here's a kicker: most doors are just brick walls and there are many of them. Unless there's an internal code saying that 90% of the time player will encounter a brick wall I'd wager there are around 20 rooms and maybe 4 actual exits, which, again, are random, so good luck spinning the room for half an hour.

I wanted to enjoy D, and I kinda did. Its atmosphere is actually pretty good and the music is fairly spooky. Thankfully the shoddy voice acting is rare so it doesn't take away from the horror. What does, however, is the twist. Oh boy this game has twists. It hits you with the dumbest thing you could think of which is unfortunate considering the optional backstory scenes, last of which you'll encounter at around the same time, ARE quite scary and psychedelic in the way I really appreciated.

By today's standard's, D is a game that is more interesting in concept than in practice. The initial hook is great: the protagonist, Laura, has just two real-time hours to investigate why her father has gone on a shooting spree, or it's game over. The game is fully-animated with unmistakably retro 3D FMVs, and the gameplay consists of rudimentary puzzles and first-person navigation. Unfortunately, despite the strict two hour limit, the experience ends up being a slog due to the slow pace of every animation that plays during traversal and interaction with the environment. The most egregious example is a convoluted "puzzle" involving repeatedly turning a wheel to open different rooms -- trying to figure out the number of turns that correspond to each room would be nothing short of torturous without a walkthrough. The atmosphere is excellent and D is ambitious for its time (is this the first game with modern quick time events?), but it's probably better to watch your Let's Play of choice than to play it for yourself.

D is one of those games where like... I can't really say it's a GOOD game, but at the same time I can't help but love it. It's pretty short, it's clunky as all hell, and it's slow, but there's nothing else quite like it. And if there's one thing D gets right, its absolutely the atmosphere. Being a game made entirely of pre-rendered 3D cutscenes, its got a look and feel I just can't get enough of. On a gameplay level, yes, D might as well be nonexistant, but on an artistic level I love D. that being said, its moreso a game I recommend watching someone else play, rather than playing it for yourself
