The tools in Roblox are not that simple and are pretty geared towards technical people. They're cool! But in this case I think there are better ways to start.
Isn’t that the idea though? To do something technical? I don’t know, maybe thousands of gifted kids are thriving at making fun things in Roblox Studio. They get through the grind because it’s where the friends are. Whereas a kid getting excited about Twine? Seems really lame, which is guaranteed to make a gifted kid only performatively interested.
