I don't think anyone is surprised by this icon. Pretty much the path Nintendo has been taking with their icons. Run with the art you find on the game box and crop it a bit, then call it a day. It gets the job done!
Looks great! I wish they would add pre-loading so I could buy this puppy. My 4 1/2 year old son is so excited. I mean, I'm excited too, but the prospect of a four-player, joy-con enabled Kirby with so much awesome is definitely being felt strongest by my boy. I can't wait to team up with him and remix some killer weirdo attacks! He really likes the idea of chaining powerups as part of a team. And I can't say I disagree!
