Hey, I wasn't trying to say the game was perfect. Your thing about the health powerups would be the primary thing changed about the game if I was developing it. Right now, you can get entirely too much health, and couple that with a strong offense with 2 missile powerups and it can be heck for anyone to catch up even if all three decide to attack the leader. However, despite this, it's still one of the better demos I've ever played, especially when you have 4 people in a game.
Edit:
Now that I think about it, the second thing I'd do is remove the seeking capability of the charged missiles. I swear, if there's anything that keeps the leader alive with a ton of health is the fact they barely have to aim in order to hit you with strong shots while you and the others are dying without much hope.
