Need improvement
First of all, you should add the preloader. The text "Wait ten minutes and then press play" caused me to laugh for some minutes -)
If you cannot make your own preloader (but I cannot believe it, cause this is an equation, that pupils study at school a the age of 10. Probably, you haven't get yourself well with actionscript or OOP-languages at all -just look through the AS dictionary, it is easy - trust me), you can download the default NG preloader.
=> 4 for humour (title screen made me laugh)
Graphics really need improvement, cause they are very simple. Walk animation is a good example of FBF, but it should be speeded up.

Sound... ok, there was sound (and it wasn't bad), but it'll be better to add some background music.
=> 3 for sound
There was some violence in the movie, so i cannot put "0" =)
=> 3 for violence
Interactivity... the gameplay is poor. It is like those old text quests but it has graphics. Maybe that's not bad, but, unfortunately, this isn't too interesting to play the game. Need improvement (maybe some inventory items? (No, the key and the gun were not inventory itemms, actually).
And it's boring to start the game from the beginning, if the hero is killed.

Improve it and post to Newgrounds ;)
