I've been playing with a customized nunchuk+remote layout, but I'm not really feeling it. Hmm I need a tighter grip, so maybe I should use the GC controller, or maybe the classic controller.
I was kind of hesitant to play as Olimar, but I gave him a try on smash the targets, and he seems quite playable. I like him. He's probably going to be one of my main fighters.
My roommate's an Olimar, some tips:
He's quick. Amazingly quick, with range, as well.
Throw the white Pikmin. They're amazing that way, and useless anywhere else.
You don't need six Pikmin if it's going to hurt you to pull up all six. Wait until you're safe to save them.
Range, Range, Range, Range, and range.
His UP+B is "magnetized," but you probably knew that. It can't grab a ledge if someone's on a ledge, even if he/she is hit out of the way of it.
Each Pikmin color has a specialty. From memory, Blue throws harder, red smashes harder, purple throws harder. I think Yellow's specialty is the unique throw path, but other than that, I don't believe it does greater damage or knockback than others.
His down+b, and maybe other moves, has/have super armor.
