I think the point of going evil is so that you don't have to worry about saving the survivors and watching your shots. If you go good, the only weapon you can use is affinity blast so you do not kill off the survivors in like 2 seconds. Evil gives you more weapon range, which can be fun.
uhhh, as im typing right now, im stuck in a glitch, where the ball just keeps falling down past the horizontal walls. cause of that i didnt do anything and got 5.8 multiplyer...cool.
wtf, so the big star sends out little stars to kill you, and then the rollie things. then the big star moves down and eventually traps you to one side, then you eventually cant move, then you get killed by a rollie thing. so...what....the boss wont die?
