Godzilla Smash 3 and something interesting I noticed!

Haven't beat me favorite app on my iPhone yet but has anyone gotten past level 27 in Tokyo? And if so, do you have any advice on beating it without using a continue, I'm trying to save my iTunes. Also I don't have a facebook account, is that important for this game?

Also I think there is a moon because all the Tokyo levels are at night.

@KING, Yes the facebook part allows you to send game invites to your friends that have Godzilla Smash 3. So they can join you and help you fight the levels. Also for having it linked to your facebook every so often they send you a free boost. Yeah it's true they could have added the moon because the Tokyo levels are at night but even then you would hardly notice the moon unless it was rotated in just the right way. Otherwise the moon is hidden from the planet or off screen. Just a strange detail to add to a game. When you look at the achievments page there are several locked achievments that say "seceret, Keep playing to find out" Maybe those have some cool unlocks related to the moon?
