Some logical enhancements

[Googolplex]

Amnesia have a really good shadow system to let the player see light and dark effects. When you throw a box through the shining light of the window, then you see the shadow moved on the ground or wall.
But why did the player have no shadow?
I think, it would be a good improvement if the protagonist would have a shadow.
When you walk beside a window, then you see your own shadow moving on the walls. The player feels like he is in the game and not only a visible spawned ghost.
It also could make a horror effect, when you see your own shadow or some tricks with shadowing effects.

An other reason is when you look at the ground, you don't see your feets.
It would influence the atmosphere when you see Daniel is walking barefoot over the moist old stones of Brennenburg castle. When you see your feets on the ground, without any shoes, you may get more feeling of an helpless guy. Not a super hero with paladin armor.

A further point is an atmospheric enhancement you can get with dark animals, Amnesia has rats what would make a good atmosphere in the cells. But what about some ravens or bats? The sound of ravens is really atmospheric and bats would be make the environment more alive and could be used as some shock effects for example. All to get is a very detailed atmosphere.
Even use high definition textures, could be photo-real.
And more sounds for creaking wooden beams or sth.
