Yeah, I managed to finish it in a little under 4 hours, and I think I completed almost everything.
The Breach part isn't actually like Breach (it's more of a tiny series of small puzzle platforming bits plus one neat segment that made me kinda chuckle), and the Blade itself is a nice big tower to infiltrate and snoop around, with lots of alternate routes and whatnot.
The story is kinda fluff (Bank has dark secrets, blah blah), and the mini-hub before you enter the Blade is a nice surprise after Desperate Measures and how soon this comes after the main game, but it obviously can't match the main Prague districts, with a bunch of unopenable doors and obvious buildings and rooms that blatantly exist just for a main story segment (I'm still laughing at how they needed some early combat/stealth areas, so they just plopped down some random armed super anti-aug people in a courtyard who don't seem to have any reason to be there or belong to any named group. I guess the Dvali were too played out by this point?).
Anyway, it was definitely some Deus Ex fun though $12 is
a bit steep for what it is.
(Interestingly, you get a final choice at the end of it, right before the final FMV cutscene and credits, which I wonder if they're going to track that for a sequel given that they specifically make it out to be a "this will help the cause" or "this could backfire on us" decision)
(Also also, the dynamic between Pritchard and Jensen is maybe the most genuine in the entire game outside of the
sidequest, Toufexis is pretty on point expressing the tone for their whole frenemies banter)
