I've played through a quarter of the levels, and noticed a very apparent design flaw: You're able to win by mirroring their moves until you're one planet away, then you can just chase their main fleet (40 or so) around with your main fleet (50 or so) until their fleet dies. They can't get any planets from evading your own ships, and you can kill off the rest by using your measly amounts of ships against their measly amounts of ships. It really breaks the game.
Does the luck stat affect how heavily weighed your chances of increasing your item? It seems that with a higher luck makes increases a hidden, second stat that determines your chances of breaking...
Ah. You don't get this type of games very much now. It soothes and relaxes you on a slow pace, and makes you want to run on the last. It combines music, art, and pace into a great harmony that only great men, and women, have found. Those men and women learned that greatness, relies in harmony, and this, does not deserve 5/5 stars, but into the Hall of Fame.
