While I like games in pixel style I strongly dislike pixel-fonts. I never felt that a coherent pixel style is worth the trouble reading hundred of lines in a text based game in a difficult to read font.
Until Difficult 60 Interceptor Spawn will work fine: 4 Interceptor bays, Reactor, many Interceptor bays. Works very well for Defense level, including final level.
That's as simple and accurate as it can get!
