Okay, what's the truck to the tower? I'm okay with the other events and tricks to get higher scores, but I never figured this one out. 

I think I got to level 12-13, but People in my guild were easily over 20. I'm normally at the top of the guild list, but not this time.I do every room and just can't get through any of it quickly. It usually takes me at least 3 rooms to even unlock the boss. What's the deal? Any advice?
