Kerbal Space Program – The First Click of the KSP Re-Root Tool Explained

According to their blog, the latest version of the demo is based off of 0.18.2. This means you have docking, which was added in .18. There are some restrictions from the full version, though:

• Part loading limited to the 25 stock ones.
• No Plugin loading.
• SPH and Runway Facilities are inaccessible.
• Only one save profile allowed.
• Cannot launch new flights if 3 or more are already in progress.
• Kerbin, the Mun and the Sun are the only celestial bodies in the solar system.

You should be able to see the version in the bottom right corner of the main screen, once the game has loaded. Currently, you're at least two versions behind.

If you look carefully, you'll see numbers on the reputation bar. It sounds to me like you're in the area of 700-1000 reputation. The pin in the middle of the display corresponds to your current reputation. As you gain reputation, the background moves to the left, and you enter the green and blue zones of high reputation. At the start of the game, you'll have 0 reputation, and the bar will indeed be green and yellow.

The striped blue area on the right is reputation over 1000. I don't know if it's possible to pass that. The areas corresponding to less reputation are to the left, and get progressively yellower until you go negative, at which point it starts to become red. (I haven't played in those areas yet, so I don't know much about it :P)

The purpose of reputation is to affect what contracts you're offered. I suspect the color zones on the reputation bar represent different 'levels' of contracts. I haven't tested this though, and the colors could be purely aesthetic.
