Yeah you ran into the pain points that I hadn't gotten around to in play testing. The hedgehog one has been mentioned before and I wish I had made that one more clear. You need to push the leaves onto the burrows in that area. Having a little "(2/5)" pop up above them would have helped a ton I think. The glider was also a tricky one. I ran into the issue of, how do you explain how to use a mechanic and keybinds without breaking immersion of the dialogue? You need to hold space while over a lit heartroot, and it allows you to glide around. Things like this I assume can only be brought up with more play testing. In my first jam, I didn't have anyone playtest and that was a huge mistake. I had wanted to put a little light at all the entrances to the different areas but couldn't sort out how to make it not look like it was above the trees. Some more experience in godot and I can get there I'm sure.
With a few more inputs from play testing I think I could of worked out all of these kinks but you live and learn. Thank you for checking it out and for the feedback! If you have some time, I'd love for you try out the glide again. It's a very cute animation and is pretty fun IMO :) and it let's you get to the last heartroot the finish the game.
