Wow! Amazing it is! I love the mood and it looks challenging too.
But I strongly disagree on the "casual" part. The game looks
really hardcore infact: Sci-fi setting, darkness, things that kill you (and the player shooting maybe). These are all things that exclude the word "casual". Even your game title is considered rather hardcore in my humble opinion.
Casual games are the ones like Bejewelled and Peggle. Watch this trailer and see the difference for yourself:

Calling it a "subjective shooter" just sounds wierd btw. First Person Shooter is the standard term and I don't think you will fool anyone into believing your game is anything else.
I suggest that you consider if you really want to target a casual market that primarily play games in a completely other style and the primary game buyer is a woman in her mid-forties who never played a FPS in her life before. Is a game portal like
this really where you are heading?
I think you might have a hit game but you are marketing it wrong.
And please, don't take this as a negative load of bull.... that I'm writing. I really hope you succeed and having worked as a level designer and tester on loads of commercial mobilephone games I have some experience with the casual genre.
