while the subject matter is a little off, should that really be critiqued (sp?) if look at it he themed the whole thing very well, and i believe it could have been a lot more immature. So its not all that bad. Great game play. 4/5
3RD to comment. i would like to see a shield of some sort, because its easy to loose the enemies bullets behind your fire. other than that its put together pretty well
It's very linear, and the graphics need to have alot more work put into them. this looks like an alpha test of your combat engine, but it is no way a lost cause. Remember that when a person starts playing they have no idea whats going on, so you have to fill them in: story, mechanics, and controls.
I enjoy the concept of the game. Like stated before, the jump should be fixed. Also you might water to consider different key binds for the attacks instead of rotating ( i.e. 'Z' , 'X', 'C' for your different attacks.
