managing makecode arcade with MS students - GR 8

Does anyone have any classroom management ideas for using MS arcade game site through makecode?

We make one game together and we do some of the tutorials but I want them to make the kind of game that makes sense to them but we run into problems with coding since different games require different kinds of code. It is hard to manage the different ways to make games. Also some kids take a game already made and barely adapt it. Just looking for ways to manage different games being made and also trying to get them to make a game from “scratch.” thanks!!
