I just completed all the blue levels. Have some 110 medals now and got that 2 million trophy... will be a while until I get the 30 million trophy, though.
The blue levels that gave me fits to complete were 25, 36 and 39. Particularly 39, that one was hard. I'm really getting the hang of the game, though.
Do you guys know how many suits there are total? I have 8 of 9 that I know of.
