Hi there,
I would love to, but I'm using commercial plugins for the camera (ProCamera2D) and there for I can't share it. Sorry.
But if you have any questions feel free to ask.
To that I can answer.
I've basically change the animation using the velocity on the Y axis when jumping. If the velocity is positive, jumping animation, if is negative, falling animation. I'm using my own plugin to change the animations (you can check it here https://elendow.itch.io/spritedow-animator). It's pretty simple in fact.
