Could someone advise if this is a suitable platform and language for 10 year olds to learn Game programming ? My kid feels that he has outgrown Scratch and he is looking for a better platform . Will GDscript be easy for him to learn ?
I haven't used Scratch but I think Godot might be one of the easier engines to get into compared to Unity and Unreal Engine. GDScript (https://gdscript.com/) is a custom language created for Godot and is similar to Python so it will be more complicated than creating games with Scratch since you will be writing out code explicitly rather than dragging blocks together. GDScript is immensely easier to use than C# (Unity) and C++ (Unreal), though.
It might be worth looking at GD Quest (https://www.gdquest.com/tutorial/godot/learning-paths/gettin...) to determine if it's something your kid would want to learn and get into. As a developer, I found it very easy to start to get started with Godot versus Unity and Unreal so it might be a fun adventure for your kid to start learning :)
I've been doing Godot development with my 9yo and he loves it. If you're looking for something with less emphasis on text based programming Construct and GDevelop are engines I've heard good things about as a continuation from Scratch.
To add to this I found these tutorials good starting points for a structured lesson with my kids. Would do about 30m-1h a day (mostly up to whenever they get bored). When we started off we'd focus on letting them run the GUI changes and I'd work on the code and explain the concepts to them until they started wanting to do the coding themselves.
After that my son wanted to switch to making his own game so we've been re-implementing boss fights from cuphead and lately he wants to make an idle game.
I've also found its fun to just get them to be part of the design process in game jams. It's really great to see the creative ideas that come out of young kids and game making with kids has been super fun and educational.
