There are lots of things to unlock and get, so playing it through once may not be enough, and you can adjust the difficulty of the level.
I like how they used the Underworld music from the first Kid Icarus game and did something like a reprise for it in some parts of the game, which is awesome because the Underworld theme from Kid Icarus (the first game) is my favorite.
I also enjoy seeing
Pit get eaten by the Tempura Wizard because... I do. I find it sad too.
I go to together mode, and if you want, I could give you my friend code for my 3DS so we can play... Also, I am trying to see if I could be flattened the atlas foot in together mode because... I heard rumor from someone whom I will not mention to protect their dignity... or reputation. I believe in him too... I just wanna see it happen to me once though.
I think you guys can enjoy it, and if you're left handed, don't worry. You can adjust the control settings in the options menu; although, this game may not be for everyone.
Oh, I've tried to be flat in Solo mode, but no dice.
