/sīn/: the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse. A perfect sine wave. Until you mess with the controls. They're simple, up and down arrows or W and S. It takes practice to control the wave. Sometimes it goes where it shouldn't. Just know that was your fault you couldn't see it.
The game will not get harder over time. The only challenge you will need to overcome is yourself, and how you control the wave. It looks like a game similar to this was on featured. Comgratulations.
