I got an A+ on hard! My score was 4412733 with a max combo of 357. I scored 258 perfects, 97 greats, and 2 goods. I didn't get any bads or misses! I was playing on 6.5 speed and had 0 crazy options on but i got 100% of the notes.
The only problem is that if you have two pizzas, and the second pizza finishes before the first pizza, then u give the second pizza two the first person, and you get nothing for both pizzas
