Inadequate at best.
The road to Hell is certainly paved with good intentions.
Plot: The plot mostly just one huge cliche, and the two parts where it deviates from the norm (the death of a character, and the reason why this can be considered a "Christian" game), are just hilarious. The end is utterly predictable, but manages to not flow with the rest of the story at all. I appreciate the game having a plot, but I'd expect more creativity from a puzzle game.
In addition, the twist at the end still doesn't really make much sense. It leaves far more plot holes than it causes. (For instance, how does the girl not recognize your voice? Why was Asian Guy in the vent shaft? Why did the bone in his finger contain a metal bit?)
The dialogue is equally incomprehensible. (If you don't see any use in the stocking, why pick it up? How on Earth did you not notice that the girl wasn't with you immediately?) Certain plot-points (The highlighted passage, the safe) are brought up, then forgotten completely without being resolved. I appreciate the effort you clearly went through given that you created a script in the first place, but the writing could clearly have been fine-tuned. A lot.
Gameplay: The puzzles were a mess. Most of the answers were hardly logical (The way you get out of the room is simply insane), and one would have to be a Monkey Island champion to think of them without some kind of walkthrough. I certainly wish to give you points for creativity, but the game just needs a level of logic to it that isn't provided. Most of the puzzles that aren't ridiculously obtuse are rather simple. The difficulty curve is simply all over the place.
The way that the game turns from a puzzle adventure to an action-adventure at the last minute is very jarring, and doesn't fit with the tone of the rest of the game at all, shattering any of the atmosphere you had actually managed to create.
Sound: The voices certainly weren't horrible, but they definitely weren't great either. There wasn't too much emoting, and at times the main characters dull monotone just gets on your nerves. I ended up droning out the music around 5 minutes in. It just felt like white noise.
Graphics: The character and background designs were plain, and in the cut scenes, the character movements make no sense at times. (Why does he wink at her when they are moving the bed?) Other than that, the animation is serviceable. It does what it needs to do, and nothing more.
Overall, it's obvious that thought (at times far too much thought) and some effort were put into this game. It feels like if it had been beta-tested, and more thought were put into the parts that really mattered, it could have been good. But it simply wasn't.
