Not that great
I gotta say i'm getting plain tired of people using sounds ripped rom Half Life (and some from CS and TFC, in this case.) At first it was excuseable, but now it seems like they were the only sounds you used at all, not counting the music.
And the graphics were humble, to say the least. You really need to cut back on use of gradients, since you don't know how to use them effecivelly in an animation (not many do.) And they made it really slow, too.
Also, the game was too easy. You say it had 4 different parts, but it was all just point and click, like Lethal Enforcers only without the light gun.
I simply can't understand why this has such a good score.
