I just tried your demo.
What follows is not a complete slagging match of your game, it is merely my opinions. Take it on board if you want to, or not....its your game.
The good
*You obviously have the basics down (keys to open doors, sound effects etc)
*You do create a sense of worry when greeted by the enemies
*That's about it unfortunately
The bad
*The lighting is non existent (now, i know lighting isn't everything - in my game, i have no lighting at all and have turned the ambience up to get a brighter overall feel, but, that's because my game is a non violent puzzler. In your case, i would say that lighting really sets the mood and keeps people on edge)
*You have over used the Lobotomy characters (3 of the same in one room - and a small room at that)
*No entities ...... at all! Except a few boxes and a skeleton in a chair.... You need to beef up your levels and add a bit of something to them. You obviously have a few model packs, grab some entities, work out what a room should be and dress it accordingly. (obviously don't go over board and throw random entities every where for the sake of having some. You need to sit down and really think about what that room is, what should be there and why)
*The HUDs and loading screens are stock. Change them. Its the first impression of any game and the first thing i did was sigh. "Oh, another game with the same stock screens and that weird droning sound when the game is loading"
The Ugly
*The first character is REALLY easy to kill, but, the three chaps in the other room are nigh on impossible to take down with just a knife. Think about lowering their health or maybe give the knife a bit more 'umph'. I tried to play this game 5 times, every time being killed by the first green guy. I got bored and turned it off. (i did try to run from them which added a bit of a scare factor as they can move pretty quick, but, eventually, i died again!)
The 'should be buried and never seen again'
*All of these quotes claiming your game to be the best thing since sliced bread. If you are new around here and this is your first game, then good on you for trying and getting something out there for everyone to see. (more than i can say about some of the people that give criticisms on these boards!) So, well done for that, you are on the right track to learn more!
But, if it is your first game, keep the boasting to a minimum.

you will love 5150"
Also, one final note
Quote: "buy it march 2013"
..........really?!
I will leave on a good point. You have a good starting idea; as long as you can take constructive criticism, you will do well around these forums. Nobody out here will say anything to be just mean; if anyone does as i have above, it is only to help you improve!
