Hey MXS!
Really cool innovative project you got going.
A few things I noticed: enemies seem to freeze once you shoot at them and not resume the attack? They seem very apathetic in general :/
I like the atmosphere but I find the visibility a bit too limited. Some sounds where repetitive after a while too.
All in all I salute you for tackeling something like this. You and synchromesh are really pioneering the genre here.
Try slanting the ambience setting slightly towards blue and the surface level slightly towards red. That should give your look a bit more brilliance n'all.
