For the hard badge, I found it easiest to not be controlling wasd game and balance game at the same time. balance the red game so that it's almost not moving then get all the squares, and also remember that you have 10 seconds to get them squares for the green game. So, if you are at >90 points, just forget about it :).
It is a fun game and all. But as people have said, it takes a long time to get upgrades. A good tip to speed up your game is to get 3 groupies, a hat, and chain tricks as it adds to your multiplier. you can get in the 10,000s pretty early on this way.
Finally,after 2 hours of solid game play, I've got the impossible badge. I only skipped 4-4 :)
Fun game but very frustrating!!! Pretty easy impossible badge tho.
