so, are you assuming that just because the game engine is made for kids, everyone that makes a game with this engine is a kid?
and now you're also assuming that every game made by a kid is automatically bad?
If you look at scratch's statistics page most of the demographic is kids and have less experience so less quality games in general. I'm also a kid.
bro chill with the twitter logic
it was made for beginners, typically kids. it takes a long time to actually develop great skill
most havent reached there yet
