Looks really good! Just one thing. If it's a sci-fi horror I think you should remove the techno music from the trailer and make it a little more unsettling. With scary ambient noise or something. Now it gives you the feeling of a crazy shoot'em up game.
And I also think you should remove the text saying "interact with objects" and "keys to open doors". They should not be promoted as cool features as that is something that players just expects to be there anyway.
It's like promoting a car and emphasize that the car has "TIRES and a STEERING WHEEL!", hehe
But that is just my opinion. The game looks really nice, almost like a scifi version of Hot Line Miami Well done!
