I ordered my copy of Yooka-Laylee on PS4 via Amazon, and they sent me a code to download something called the Yooka-Laylee Toybox+. It's just a demo level that's filled with a bunch of geometric shapes, like a VR level. And when you get all the feathers in the level, you can view a secret that's in the actual game that's probably all over the internet by now anyway.
From the demo, I'll say it mostly plays great. Except the move where Yooka rolls and Laylee runs on top of him feels too slippery. I think they were trying to imitate the move where Kazooie walks fast, but controls in Yooka-Laylee just feel slightly more loose to me. If there are any ice levels in that game, they are going to suck! But I'll just have to see when I get the game.
