Very nice work! This wasn't necessarily my favourite type of game, but I give it a maximum vote for how well made it was. It was also funny how this reminded me of Doom 3 a bit.
Although the art was far from the best, there was a lot of detail (objects, debris, damage, etc) and you can interact with a lot of things. The game was long enough and the world was larger than what I find in most point-and-click games, with a lot of items and cutscenes and voice acting for nearly every action... the effort there is very laudable! It also has several endings and a few well hidden secrets, which take either a lot of thinking or a walkthrough to get. The idea and story are also below average, and easy to understand as you go through the world.
Also an opinion on some comments below, saying this was bad because it failed at being a good horror game: I don't think this was intended to be the most horrifying game in existence, but rather to take place in a creepy environment with a few scares here and there. This had other strong points, which I think some people totally ignored in search for the perfect horror factor.
