First I'm new to the series and this is my first katamari game , I've even looked at zoopsouls youtube walkthrough for the 100 points stuff and I feel like I'm rolling my ball the same way he is but in the end i keep failing

My highest points on almost every stage would be 75 but however on Shani Circuit i would get 93.

Do you just need to have strong hands to get 100 points or what ?
