Nice game. The story is there, and the visuals are there. However, the game gets a little easy and repetitive after about 20 PACS. I see they kinda speed up a little bit, but simply adding more PACS on the screen at once will add the difficulty previously missing. A simple clone script should do the trick. The health pack adds a nice touch of diversity to the game. And impact feels dull. When a PAC hits my SHIELD, I should feel it. An animation that plays when I kill a PAC would make the game feel more dynamic. Great game all around. Keep it up!
