I didn't meant to offend you, but I guess you've posted your project here, to receive some criticism.
Game is to linear, I mean, all enemies are acting the same way, only two kind of weapons etc.
You should consecrate more on gameplay. I turned off the game, as soon as I died..
Make some idea for game, not simply go from point A to point B while killing everyone..
Make in as in old games, like find key A to go throw the door A, etc.. Make elevators and so on.
