Kardashev Scale

HOW TO WIN: You win the game by constructing all the dyson sphere segments. You already start with 1 segment and you need to build an additional 7.

There's a grace period before enemies start spawning. I recommend focusing on building energy production first and once you are down to about 100 mass, start building both mass and energy production.

Your space station should be able to handle the first wave on it's own or with the help of a single corvette. Afterwards you'll want more ships to soak up enemy projectiles and protect the station.

Don't build dyson segments until your economy is really strong, as there's no benefit to having any number of segments other than winning the game.
