this is really good. more of an adventure type game than an fps, which is a good use of efpse.
feedback:
1. i think the geometry would look alot better with the use of the angle tile ( 
)modifiers in places. this would make it feel less boxy. unless boxy is what you were trying to achieve!
2. fog is too close to the player in my opinion.
weird / ridiculous / humorous setting and concept is cool. with some simple scripts you could do some more nifty adventure game stuff with this game.
