Thanks Bullstorm. To add to your hopes, I'm already starting on the full commercial game version. I have been playing around with the character controller first to improve it, and slowly I'll build up the other concepts. LOTS of research for making the roots grow randomly to generate the roots and ground for unique experiences, taking everyone's wonderful feedback to heart.
Here's the link to the new character controller in action so far https://guildedhut.itch.io/verdant-heart-sandbox I'll re-add the double jump soon. It's already in there, just toggled off at the moment. I was focusing more on coyote time and jump buffering.
