To get the badge you have to be super lucky. IF you don't get about $28 in 28 seconds in the first round give up. Get a parcute over a e pack and flaot down getting time and coins and dodging everything but a $10 platform.
Get A INFECTOR AS CLOSE TO THE ENTRACE AS POSSIBLE BUT WITH STILL GOOD RANGE and then upgrade it with fork, linker, and memory leak. IT owns and can actually beat the first couple waves a round by itself and least for the first few levels.
Finally it took me 3 hours to get the right combination for the hard badge.:)))))))))))))))))))
To help others:
1. the easy one is easy just do the songs and you should get it
2.for the 4000 shapes badge do pattern:straight and motion: fixed remember you only get the badge if you do leaves of the wind. Go to a side to side motion and when you get bigger you can get all the shapes.PS randomize off
3.to get 100x in gentle do the setting above except on the song gentle. When you get you yellow madness stop getting shapes and wait until it get to the bottom of the screen to get it to maximaze yellow bonus.
4. the hard badge is really hard because its mostly luck.I finally did it with the setting above and then just reseting the game until i got my yellow madness in the first 5 seconds
A tip if you have purple power and you get hit by a red you get all your yellow things back and you get points for them again.
To get the badge you beter hope you get purple power and yellow madness at the same time
