one tip that may help.. i bought a really strong right rocket and used it to travel right at highspeed for a good distance bonus... didnt buy any other boosters ... except the emergency rockets .. mostly though.. you just need luck to hit alot of platforms and geet good cash bonuses
seems like dumb luck if you get the hard badge or not... i cant get up to 60 multiplyer.. yellows just dont show up enough before the main stream of shapes show up.. even after 20 games
hard badge is being difficult.. for some people its easy.. like 80x multipliers... i rarely get close to 60 .. im not missing any... they just arent showing up ... randomness.. blargh
S-Mart Shopper! .. shop smart... shop S-Mart .. evil dead reference for the win ...... basically just stockpile ammo and blast away like mad .. and hope for a nuke or 2
