This game brings me back to me youth on the Apple II! I love it, I've gotten quite addicted. This is from an era where games were NOT intuitive, and were just plain difficult. These days, games hand-hold you though the whole process, leaving little to be discovered.
This game has frustrated me countless times, yet I keep coming back to try again! Those of you who played any of the Gradius games (Especially 3) will know the feeling I'm talking about.
When it comes down to it, the game is very simple. A little bit of strategy and planning mixed with a bit of micro management. Turn based play ala Civ 2, but your building up a space program from the ground up!
My only complaint is with un-uniform key commands. I wish escape was the universal cancel/back key. Currently, escape is sometimes cancel/back, and other times you must use 'e'. Other times there is no key at all, and you must use interface buttons.
Glad to see classics like this being kept alive. Good work. Oh yeah, net play is a slick addition!
