This is a dumb thing I noticed, but since they're in the final stages I might as well bring it up:
When Yooka and Laylee meet Scoffsalot, they're in a dark area and a spotlight shines on him. It reminds me of something that might happen in Nuts and Bolts, because it makes the situation look like a play instead of a real conversation. Especially since Yooka and Laylee stay lit by the actual light.
That being said, I'm just being nitpicky because everything else they've shown looks so good. I hope they don't reveal anything from the other 3 worlds now that we've seen parts of Hivory Towers and the plow transformation.
