Jungle Jump Player Animation perceived problems

[mrwnphs]

I spent a lot of time debugging the Player Animation because I misinterpreted the following two sentences:
"This would be a good point to stop and test the player to make sure everything is working. You can’t just run the scene, though, because the player will just start falling without any surface to stand on."

I actually tried to test the scene and it appeared to not work at all- no falling, no moving left or right. But of course, the real problem was that I hadn't yet created the Main scene with the CollisionShape2D. The Camera is what through me off. With the Camera on and no background image, it just appeared that nothing was happening. When I turned the Camera off, I could see that the player was freefalling and that left and right movement worked just fine.

Maybe consider eliminating the first sentence, "This would be a good point to stop and test...", in the next edition?
