You already got quite detailed review, but I will write mine anyways so you can cross them to get all the info you need to make whatever you want to do with it ;)
-The graphics set up the atmosphere alright, the animations are good, the sounds is good.
-The camera is a bit of a problem, it is hard to get the right angle. Imo you could make the arrow keys controls the camera angle, that should do the trick, as there is no other use for the mouse I think.
-The UI are different from the rest, which makes it look out of place / unfinished. Too bad because if the story is quite classic, it is always a good feeling to see we are breaking free.
-Maybe add a pause panel, where we can find the controls, or go back to menu (which would means a save of progress)
Anyway good entry :)
