Yeah, making this game was an adventure :) I deleted my first game after two days, when I realized that it was the least fun game I ever made, and went with the planet idea.
Then I made about 95% of what you see before Monday, planning to add/polish stuff later in the week, but suddenly my job became very intense, and the only thing I managed were some really slight changes.
The idea I had, was that you would see other players' planets in the distance, and maybe even interact with them in some way. Since I had no time to do that, the only interaction with other players is at the end of the game, with decoding the message and deciding what to send in your space probe.
Oh well, maybe next time :)
