Having conquer the level the game tells me, 'The heart of this asteroid belt has revealed its secret. We have learned much and gained a new weapon. I must now send you further into treacherous territory. It is time to face THE OUTER COLONIES.' Which is great. So I press the OK button and nothing happens. The level is never flagged as a win and I cannot move on to THE OUTER COLONIES. What have I done wrong? I have just finished the level again with the same result.
