It's tough to add badges to this, as you can copy paste your link with saved data and put it on the web. Everyone could get instant badges if that feature stays =p
I've been having a lot of trouble with low gas levels, and ppl if you say it's not an issue then you got lucky. The problem is that you hang in the air for too long, and xp does not update until you hit the ground. Leveling the two planes with homing missiles last helped me a lot but I still died at the end for not getting enough xp even though I dodged almost every homing missile. Still find it fun, too bad I always die right before I max the last plane.
