I played a lot at the Splatfest. Just enough to get to Cat King. Very amazed at how Nintendo is dealing with this game. A lot of support and interesting twist on the game.
Getting those Sea Shells is pretty cool. I love my "Robot" equipment but the 2 stars was a bummer. Now I can use the shells to add the missing slot on those and keep playing with them.
I also finished the Story mode now and I'm almost level 19.
