Alright quick thoughts after playing an hour
Love it.
One issue to talk about for now and one two minor nits:
Main issue are the see-saw platforms. For me, personally, there was a bit of frustration in getting up them due to not knowing when my jump would be enough height to get up versus a LT+A ("flutter") jump. I would always not quite be level with landing a jump, even a fully tilted platform.
What I kind of miss in situations like this is a ledge grab ability (I know, I know, Mario 64).
Because Yooka grabs onto Laylee's arms, will Yooka not be able to ledge grab and pull Yooka up?

In the screenshot above, on the see-saw platforms at the top is where I can't make that jump unless I LT+A ("flutter") jump.
My minor nit is the weird fishbowl barrel CRT distortion effect under-water.
Second nit, rolling turn radius is wild. Wondering if that will be honed in a bit for better control.
