User blog:Sungj/Advice for a new player

Hey guys, I've been playing for a few days and I was just wondering if anybody has any advice on the most efficient way to progress, what chapters to focus on and just general information on who level up, where to use XP etc. As a reference point I have all basic cats at level 10, all extra upgrades ( cats wallet, cat energy etc) at level 10, 1 uber (Uesugi Kenshin) at level 9 and a plethora or rare and super rare cats. Any tips would be appreciated as I can see this game is a long grind kind of game and I'd hate to waste resources and time from mismanaging my early gameplay. Thanks :)
