You play as circle, a sentient... circle, as you traverse the great expanse of Graphtopia. Water is made from fluctuating sine waves, which you can clearly tell and is totally not impossible to know with how pixelated everything is. Like what are you talking about. You are trying to survive while being attacked by ((abs(x)-0.4375)^2 * (abs(x)>0.4375) + (abs(y)-0.4375)^2 * (abs(y)>0.4375)) = 0.0625^2, or as I like to call them, rounded squares. You fight to survive using your trusty trigonometric functions: sine, tangent, and cosine (which looks identical to sine but together they make for a circle combo).
