Well, it worked for me.
I would say that the game needed at least some basic shading, this would soft a little the differences between photo-textures and drawn-textures, besides the shadeless things (as characters) don’t help for this kind of game.
The game controls need some severe fixes, the mouse is in fact over-sensitive and the attack in fact works bad (unless that’s the idea seeing the plot XD, but in general this ain’t a good idea).
Modelling in general is good, and even if textures style is mixed the environment and music gave a creppy feeling.
Talking about textures, they need to be optimized for game making, most of your seeming too high resolution, remember that no matter how big you put a texture on the BGE, it will be rendered downsampled because of graphics limitation, you got to make them as power of 2 (2x2, 4x4, 16x16, 32x32, 64x64,128x128,256x256,512x512,1024x1024)
As Helloo said, the erotic stuff on it is way over the top, there a huge difference between mature and … well you get the idea, and there may be people who wont like the idea of fire fighting on a church, there are children, and their parent looking besides them sometimes, that come to this forums you know? There are other ways to show the same ideas.
Besides that, Is nice when someone gets to end a game, keep blending. It can get better.
