Understood and cool, no need to throw in katamari music if it's against your vision for the project.
I thought I'd give my take on the criticisms mentioned in the log ...
Tutorials - I don't have a strong opinion. I don't see a need for more tutorials, but then again I was the one who began the Ace battle with everyone pooing their pants, lol.
Swearing and humor - I haven't seen any humor that's problematic to me, but I still haven't tried most of the quests (sorry). But I still think the swearing doesn't fit. In my opinion the game would be better if the S word didn't appear in it. It's your call though, and the game is also good how it is.
Repetitive gameplay - Personally I really like the gameplay. :) Yes it is repetitive but that's not a problem for me. Real katamari gameplay could be called repetitive. It's worth listening to other people's opinions though, and I sure have nothing against adding variety. I hope the gameplay doesn't change too much.
