Movie Maker mode in Godot 4.0

Only sad aspect is that I eventually converted to Godot 4 and now I'm stuck with it, but can't publish it for them on iOS because that part is broken for a few months now.
There are a lot of things to learn in Godot. I leaned mostly on their own documentation and maybe a few YT videos here and there for certain effects.
I would very much recommend 2d to start, there was a lot of fiddling with trigonometry to get the camera and things working in 3d. Really not hard but might be frustrating for a kid if they haven't been exposed to math like that yet.
Other than that, just get started. I would recommend finding examples of similar games before you start. For my second game I just took the FPS tutorial and hacked at it until it did what I wanted. Much easier than starting from scratch and lets you dip your toes into the concepts you need to while being able to ignore the rest for now.
FWIW, you don't need to do that. There are functions such as look_at which do that for you.
But yes, you can certainly get away with very little math even in 3d games.
I'm not sure how much direct feedback I can give but splitting up art and programming (oldest sits next to me and gives me instructions) is quite fun. What makes Godot particularly fun at this is that you can poke around in the inspector as the game is running for fast iterations and changes.
I've loved Godot since 2, and I didn't even know this was on the radar. Good stuff!
