When you press the arrow keys, you move in the opposite direction to what you press. For example: right arrow makes you move left, left arrow makes you move right, up arrow makes you move down and down arrow makes you move up. (Pro tip: keep moving through orange hoops and don't move through blue hoops, or else you'll get hurt.)
I am thanking my cousin for her amazing support. She played this game every time I added to it. :D
