Hello! That's a bit weird. We never had that issue.
Just in case, take a look at the video we uploaded, it's the tutorial. When you hit play, it should take you through a scene where they talk (we didn't have time for images) and from there, you'll go to the tutorial fight. He'll give you the items to equip, and then the combat begins. The controls are always on the interface. At the beginning, you can't do anything because you don't have any items.
