Quoted from Guinnesstime:it's just trying to reach Alien Invasion over and over.
I know there's a ton more to do, but none of it is easy to start. I mean, Pretzel? I'll never see that.
Try this instead of Alien Invasion to make TSPP new and fresh...
Start and FINISH as many modes as you can in one ball. It's just a right orbit and TV loop to start a new mode - fairly easy to start modes.
Do them all and each shot is worth over 7M. And with double scoring going, you can explode the score. It's harder than AI. But just do 3 or 4 and your score will skyrocket. Gotta keep the timer going though.
Also, if you just wanna play Pretzel, you can get it by focusing on the shot. Unlike SDME Wizard mode, Pretzel is not impossible.
