I've just been playing the demo. A couple of launchpad disasters; a perfect sub-orbital flight marred slightly by forgetting to deploy the parachute on re-entry; an attempt to circularise orbit while pointing directly at the ground (that didn't work too well); and one successful orbit of the planet, followed by aero-braking to land (periapsis inside atmosphere), because I ran out of fuel.

I think I'm ready to purchase this thing.
