cool game sir,
i like the look of the graphics, and the feel. movement is a little tight in the rooms, but that is probably on purpose, and forces thinking, which is always good.
if you could make the gui at the bottom a more contrasted color, that would help it, to not blend in with the scenes when you checking quickly for weapon or ammo status.
but i really like it, would be even better if larger in scale, as far as window size.
keep going...
