Do We REALLY NEED to follow them @ Twitter & Facebook just to get the last 2 stars for the badge!!?? This is absurd.... I mean, SURE, the game is AMAZING and I have even rated it with 5 stars, but what if someone doesn't actually like the game & just wants to get the badge? Sigh...
For level 58 use : shortshield and lightning.With only those 2 weapons you can win level 58.But in case you are stuck , use slow time as the 3rd weapon to dodge when needed much easily.
For the last level of the game use :
1st weapon : Energy Homers
2nd weapon : 4 Homings
3rd weapon : Duck Death
Use duck death everytime it's ready and try to stay near corners.
Since every of your weapons track the boss , there is no need to target him....your only job is to dodge and click to fire :).
