well... The demo was ok. But the enemies were really easy to kill. got trough the demo without taking any damage. And I knew where they were going to spawn becouse their shadows were showing on the place before they spawned. And if some model with a shader is dynamis, don't turn it to static, cause the texture wont be showing, it will be this weird mush. And in here, there was alot of these objects. And in the starting room, some of the furniture stand out very much, like they were glowing. And you could see the skybox from the vent in the start in the 2nd level. And in the first level, there was these 3 doors and in the second one you find the key. That room was dark, and you couldn't knwo that the key was in there, so I just looked in there and continued looking around, until I came into that room again annd went inside the room, I found the key by accident. And in the 3rd room (in the row of the rooms with wooden doors) there is no ceiling. And there was something other too that I just don't remember.
But there was good things too. It scared me a little bit one or two times. The atmosphere was good, liked that. And the one place where you needed to find the key by going on top of the truck thingy that is holding the plank thingy was nice. But that's kinda it for the puzzles, bacouse every puzzle was finding a key. But graphics were fine and level design was good, and the enemy placement was ok. There is alot improving to do, but the demo was ok. I liked the menu screen, loading screens and game complete screen. Althou the 1st loading screen has a weird disturbing sound on the background. If that's what you ment; that is would be disturbing, then good job, becouse it kinda gave me goosebumps, becouse it was just so... uuugghhhllghlkj... Well it was good if you ment it that way. But the loading bars other colour could be more clear, ao that it would be easier to see where the progress is going. But it was ok.
I'd propably give it 07.50 out of 10.00
But keep working on it and you might even get yourself a 9/10 game, cause I can see this has potential.

Keep it up, I want to see this progress! Thumbs up!
God, grant me the serenity to accept the things I cannot change,
The courage to change the things that I can,
And the wisdom to know the difference.
