I was really hoping this game would have a Level up system like the other RPG Mario games, like making Mario's attacks stronger, it's what I love about the Mario and Luigi series, like, whenever I play that game my first instinct is to kill every foe to level up, which in turns makes me stronger. I had joy in that, but take that out and Battles start to become a hassle, they might be fun at first but overtime you'll be finding yourself think "Ugh...I just want to beat this level"
And resort to running away from almost every battle, stronger enemies will start to get annoying, but in M&L when you get to stronger enemies you're most likely think to yourself "Yes! More XP", but nooo, in this game you get annoyed at how long these characters take to kill, and once you beat them, what? just more paint, no XP...
I really hope Paper Mario goes back to its old ways, if no, at least add leveling up, that'll make the game better for me! :3
