Pro tip: if you want a method of playing that makes the game way easier and way more fun, use both your hands. keep your left pointer finger on S and left middle on A, and on your right hand put your pointer finger on the up arrow key, and middle on the right arrow key. don't look at the arrows on screen as directional inputs, visualize them from left to right as simple indicators telling you which finger to tap. makes rhythm games a whole lot easier and more fun to play :)
