I was gonna rate you low on the bad music choice
Then I realized that I had another flash load at the same time with really annoying sappy electronic music, and didn't realize. So you don't get low points for annoying music.
Let's see.
The graphics were stick figures, and they moved kind of sluggishly, that's why I rated that low.
Style you got points there because that really cool crosshairs thingy in the menu, for one - that's cool - and the game in general was pretty cool, although - once again - the character's movements were sluggish, it was like the whole game was happening in slow motion.
Sound - Appropriate sounds, not much I can say there - it worked.
Violence - Yup, it was violent, nicely done.
Interactivity - yep, although it was sluggish.
Humor? Didn't really see any, so that's a N/A.
One thing that kind of bothered me is that I wanted to be able to re-raise the flag. I understand why you can't, but it just seemed weird to me, if they can lower it, why can't I raise it? Perhaps it would be better if you can raise the flag, but you have to stop shooting to do it - and the lower the flag is, the more bad guys come after you. It would add more excitement to the game.
Good job tho.
