Can I make an entire game in UMG?

Hi, I’m looking to make a 2D mobile game that is very dependent on the screen size and aspect ratio. For example, the gameplay buttons/elements would need to spread across the entire top of the screen and change size/position based on the device in use. It seems like UMG would be best for this, but correct me if I’m wrong. Is it possible to create an entire game solely in UMG?


Of course, you just have to know well the UMG editor. After you put your widgets on a empty level and that’s it.
