Not bad
Interesting concept and game, but I think it has a lot of work to go before you can call it polished. There's at least one major bug that I found and that involves the 'action scene'. If you switch guns as you're reloading, you'll be completely unable to fire your weapon for the remainder of the scene.
Also, it's nice to have the 3D models and environments and everything, but since some of the smaller models (ie. ammo boxes) aren't very detailed or blend into the scene too much, you can't really tell if you're supposed to pick them up or not. I know the cursor blinks to tell you it's interactive or not, but some of the sequence of events aren't very intuitive.
Also as many others have stated, if you're going to have the game in English, it's best to get a native English speaker to do your translation if that's the case.
I'll finish my review in your part 2.
