This is almost something really great. If you look at it from a mechanical perspective, there's neat stuff there with the scouting and the gunplay can feel pretty good, but it's ultimately too shallow and short to really get into it.
If you see it more as a mood piece then it has amazing moody visuals, but the soundscape falls short of that. There's only a rain sound effect that feels way too quiet to me, and some emotionally empty shopping mall muzak. The fast movement speed also doesn't help with immersing yourself in the world.
There is a lot to love about this but I also feel frustrated that it's not quite what it could have been.
