Nice trailer video. Finally a plot of some kind LOL.
I want this game. Woolly World restored my faith in Yoshi platformers and I got both the WiiU and the 3DS version of the game. But, I have to admit, the custom colored Yoshis to play as via either earning the Yarns OR scanning amiibos was the real hook to the game. The 3DS outdid that by giving you the Yoshi Creator feature, of which I made tons of Yoshis to play as. This game is apparently not offering that kind of thing.
It will be interesting to see how Pipe Cleaner Yoshi's look compares to Woolly Yoshi.
From all those extended play videos on this game, I have no doubt there will be tons of secrets and interesting level designs.
