"20,000 Light Years Into Space" is a single-player real-time strategy game with a "Steampunk" science-fiction theme. It was written by Jack Whitham for Pyweek (March 2006), which is a week-long game competition. Online updates will be made available on the official website.
Reviews of the Pyweek version are here. The game has been improved since then, and more improvements are planned.
During the game, players must focus on building a steam delivery network while under attack from various hazards. Once you have solved the three difficulty levels, you can attack the high score. The game includes an interactive tutorial and a written manual.
