oh... I get what you're saying now, droe. Oh well, too late for me. I beat the game playing straight though, and used my star point thingies for resource stuffs. I didn't want to put too much more time in the game, so I didn't redo any stages. :P
Just finished lvl 10!! omg that was hard. I managed to use battleships when the Yamato was at a distant, but once the Yamato didn't have the cover of its base's AA, I sent only bombers. I killed it with my base health at like 115!! Once Yammy was dead, I immediately used my resources to put up a fortress and protect my base. My base health was 97. Smooth sailing till then. Only 3 bombs and 2 battleship shots to finish off red's base. awesome game. :)
