I have just downloaded the new version and I don't know how to start the game :( I'm stuck on the Contracts and Upgrades menu and I've got no clue what to do
Hi Nerae, so first thing: hit the "p" key to get out of the contracts window.
To find contracts, a source and a destination need to be selected. When in the contracts window, leftclick to select a source, and shift-leftclick to select a destination. Rightclick will rotate the map around.
I'll come out with a game guide this week that goes over these features more. Keep in mind the whole contracts thing is very early in development.
