Incredible
This such beats my stickmen! This is one of the best games on newgrounds. Maybe, though, you could make it location-to-level, each location having different challenges, such a flying object that ignore sheilds or a current that pulls your little helper to the end of the screen. Also, you should advance by taking out the red blood cells. More upgrades would also be nice. Still, I'm asking too much. It's sweet as it is.
Oh, yah. WUZZUP!
