Nice improvements! I especially like the new robot and parasite model. The new camera angle is also much better. However, I did get frustrated at not being able to rotate my field of view easily. Great sound and music! Really adds to the atmosphere.
Some issues: It seems being discovered on the first area crashes (freezes) the game. This did not happen in the second area. I was only greeted by a black screen when exiting the second area. So I'm not sure I saw the whole game.
Good job :)
