About half a year ago, I bought Kerbal Space Program while it was on sale on gog. I've played it about 5 hours and I don't really feel like there is a point on playing it more. The problem is, I have no idea what to do. I tried building a rocket so I could orbit around Kerbin in sandbox mode, but it wouldn't even lift off. And guides I read or watched like control the speed or other things like that. I just have no idea what to do.
