Deep Blue, as some folks have pointed out (a long time ago), is not to be played in the traditional manner.
If you do, you will immediately become frustrated. As I did (when I miraculously made it pretty far playing the game "wrong", only to be frustrated when the swarms of enemies never stopped).
So, while I don't like Deep Blue, it's because I have only approached it and tried to play it as a generic shootemup.
Believe me, it has all the trappings of a generic shootemup, with a DARIUS-inspired theme.
But it's not.
For example, I thought the trick to the game was figuring out when to use/not use auto fire. Maybe occasional moments of dodging. I was thinking about trying to destroy lots of enemies for a high score.
But that's not it.
Not at all.
The point of the game is survival...that's it. And you can supposedly recharge your life meter, too (I have never played this way, so I'm just passing on what folks have told me).
The only reason I'm bothering to post this is because _____________ is not here to do so himself. Or was it majors? Or _________? Or __________? Anyway, someone once unlocked the Key to Deep Blue. Now, you, too, are responsible for passing this knowledge on. I am serious.
