Cutscenes

how to make cutscenes like the ones from "planet repair squad"?

You can set a game state that means that the game doesn't update while the cutscene happens. When a cutscene happens, you can use a timer to time all the events in a cutscene or an animated sprite. You can also use multiple sprites in a cutscene if it is being used with a timer. You can then make them move around and interact without player input when certain timers reach zero.
