Not bad but quite a few annoyances.
1. Sliding collision with diagnal walls is pretty bad. It jerks all over the place.
2. There are quite a few places you can walk through walls and get stuck. Specially at the ends of those cylindrical tunnels. I even managed to walk through a wall and fall into space.
3. If you press escape to quit game and try to start a new game, you get either an error because an image wont load or game starts ok but you dont clear the fact you have read initial message and so cant do anything!
I like the lighting effects except you can see edge of plains you use which looks a bit odd.
You can also see a little cube at your feet. Presumably this is to assist with collision and will hopefully be hidden in real game
Guns definately need replacing. They should really be 3d so they react to light as well as you move around. Muzzle flash is far too big in my opinion.
Stars outside of windows just dont look real enough.
That's enough comments for now!
If your mansion house needs haunting, just call Rentaghost!
