Yeah, I'm still in the demo..haven't gotten nearly as far. Been playing around for the last 30-35 hours. Finally started orbiting the Mun after doing the tutorial. Had lots of fun just building rockets to see how fast I could get. I think I've topped out at 30km/s...orbiting Kerbal. Little nervous, I still can't seem to figure out the initial orbit of Kerbal, to launch myself onto the Mun. All in all, seems fun, just a little worried about content for me to do stuff with.
