Quite liked it. Liked the lack of a 'true' story and more imagination based (Though it's silly that the colors are fighting one another in midst of the black). I was finding it relatively easy, personally, in the beginning, until the blacks showed up. Then I had to play each level like a bajillion times. It was fun, but I felt a lot of luck played into it (IE, whether the other colors would target you or each other in the beginning for a good start)
Update states prestige bug of sorts where board prices didn't "reset". Is my lawnmower supposed to be ~42m for the first one, 4.6m animal jumping, 100k for Brickout, etc?
