Katamari is one of my favorite game series. Once I figured out how to play, I had a really good time and I see potential. I think you just need to work through the UI and you'll have something cool. IMO, you should play through "We Love Katamari" for the PS2 and really focus on their UI system, how they use sounds and graphics to communicate to the player what is good behavior and what is bad behavior. Would love to play again, keep it up!
