This is a story-first sci-fi AVN. It's paced how the player wants, and there appears to be no real forcing of replay (though you might want to because the story is solid).
If you are a looking for a sci-fi story-driven game, where choices matter a bit, but aren't game-crushingly bad, you've found it.
Jestur is a wizard with art. The dialogue is deceptive, in that smart characters will speak with a level of intelligence, but others will speak with a moderate level of intelligence. The line between the two is blurred by the use of casual speak, leading to a need to pay a bit more attention than you might otherwise. (No harm if you don't, the story still rolls on, quite well, on first pass.)
The width of characters does mean that a lot of the standard trope-type behaviour happens, and a lot of them are shallow-depth with stereotyping used to shade around them. While this sounds like a bad thing, it allows the audience to wind down while playing the game, and let their imagination run wild. I suspect Jestur has done this to allow for juxtaposition later (as it has happened already a few times), leaving a lot of character detail aside, and allowing us to make assumptions instead.
I'm a story-first player, so I'll say that the story is spectacular. Because Jestur has been clear that the story is already mapped out, I'm comfortable saying it, alone, deserves five stars.
The animation and scenes aren't all that important to me, but I'm not going to deny that all of it is exceptionally well done too, and, from an art perspective, deserves the full five stars too.
My only real gripe is the character depth, but as I said above, I'm pretty sure Jestur is toying with us, so I'm giving it the full five here too.
As usual, bonus points for designing it in a way where we don't have to replay it to death to see every scene.
