Thank you so much! It was rather tricky to figure out, I'm glad the gameplay turned out okay!
Did you manage to try the side quests? If so, how were they?

I went back and tried the quests ...
Ichigo's and Macho's quests were good. They made me explore a little and find a good place to grind for both. Opeo's quest is funny and a good katamari reference. I haven't cleared Ace's but a harder version of the first battle is a good idea. I may try some more but for now I'll take your word for it that it's possible. I don't know the moves very well.
All in all the side quests are cool, and having each party member/obtained Cousin ask for a quest is a good idea.
