Ok a few problems...
Alright, the game is alright but i have a few issues. I think you were going for like an old school arcade shooter look, but still i would like the graphics a little smoother. Also, because you only have 5 bullets per clip, and the reload is instant, i had to constantley press the space button every split second to keep shooting. If the reload is instant, you should just make it so you never have to reload, this wouldnt make a difference in gameplay except just not having to constantly spam space button. Otherwise, a good game with a pretty cool story :D
