Controls are very easy to use, in fact, if you have children at home, it can be a good way to have fun.
Animations are generated according to objects (backrounds, pictures,...) that can be programmed o perform certain actions.
Programming those actions is not difficult, because you can use a graphic editor hat minimizes dificulties when programming those actions, movements, sounds and modify the behaviour of the objects.
Games, animations, representations,... everything is possible thanks to Scratch.
Finally, you can add as many objects as you want and edit them.
