had 1948 ready to be 4-starred on my first try (only had the big slow moving plane left) when I found out that one of my planes was too close to the edge of the screen, and couldn't steer it away. The plane crashed. Lame. How about some sort of warning?
To get the gold, you need at least one "angel doll." Get level one "start with random accessory," then just restart the level until you get it. Put it on a mushroom that's going to be doing a lot of killing, and you'll have the gold, easy.
great... so I get down to the last few areas and it's literally impossible because their units are at least 5x stronger than mine. Apparently I'm being penalized for beating the other areas so easily and not racking up the gold instead. Still, I'm not sure that would have mattered.
