Often times, new players tend to play with the default controls, which is perfectly fine. However, to take it to the next level, you can go into (Settings —> Controls) and customize all the buttons to your liking. The beauty of this game is that you can move anything and adjust almost everything on the user interface to your liking. The game gives you the option to move, adjust the opacity, and resize the buttons to your liking. As you can see in the screenshots provided, I moved and resized the buttons to where I feel are best for my fingers and lowered the transparency on many of the buttons so I could see the screen better. I recommend you play around with it and see what is best for you!
