Okay, we are all entitled to our opinions. I happen to find the voices entertaining. The only "wish they hadn't" thing I have is the characters constantly shouting when hit "OO" "MAMA MIA!"
"DO' NOH!" ...that is a bit irritating, but I love the opening voices and bosses talking. I guess the designers played GAUNTLET and just felt they had to shout 'ow!"; I also agree the "carnival ferris wheel" adds nothing as it is not challenging, but it doesn't detract either. And too bad they didn't replace the vases with pipes to make it more "mario-ish"....
I still love the game. To answer your question, the ACE coins: you must collect FIVE in each level for a perfect score (I usually ignore them as I don't play for points).
