I was playing the KSP Demo on Steam, and I made it to just the brink of space, and suddenly when I turned down my rocket to half-throttle to save speed, it started falling back to earth, and due to a miscalculation of height, the Kerbal was unable to detatch and deploy a parachute in time and died.
Also, are the re-entry effects I have seen on videos mods, or is it just me or does the demo not have them? I've re-entered Earth a couple times and there were no re-entry effects like flames or anything.
