Aestheticially it looks great. They've done a very good job at showing the setting in an immersive-looking way.
But beyond that, I think it looks pretty poor when it comes to the actual game itself. Wonky psychics like the Ambot at 1:03 just flipping into the air, a complete lack of enemy reactions (the Ogryn at 1:08), an overall arcadey-ness and floaty-looking combat that looks like it does have much depth, enemies throwing out giant glowy boxes everywhere, unfitting "critical hit!" text and such, poor readability....
It's like when it comes to the look and feel of the setting they've managed to do that absolutely fine, but when it comes to adding substance and realizing the idea, that's not gone well at all. It's such a shame considering how great the idea and those aesthetics are too.
