I have written this code.

```auto
int x;
int y=241;

void setup() {
  size(800, 400);
  background(0);
  
}

void draw() {
  cave();
  stone();
  clumsy();
  
}

void cave() {
  noStroke();
  fill(160);
  rect(0,100,width,200);
}

void stone() {
  color c[] = new color[3];
  int n=0;
  c[0]=color(255, 0, 0); // first color
  c[1]=color(0, 255, 0); // second
  c[2]=color(0, 0, 255); // third
  for(int i=0; i<width; i+=30){
    stroke(0);
    fill(c[n]);
    rect(i,100,30,30);
    rect(i,300,30,30);
    n++;
    if(n>2) n=0;
  }
}

void clumsy(){
  fill(0);
  ellipse(x+30,y-5,80,45);
  fill(#F3F156);
  rect(x,y,58,58);
  fill(#90F614);
  rect(x+5,y+10,10,10);
  rect(x+40,y+10,10,10);
  fill(#EF1A1A);
  rect(x+15,y+30,25,15);
  x++;
  if(x>width){
  x=0;}

}

void keyPressed() {
  if (key == CODED) {
    if (keyCode == UP) {
      if (y == 241){
      y-= 100;
      }
    }
  }
   if (keyCode == DOWN) {
      if (y == 141){
      y+= 100;
      }
    }
  
    
 
}

You need a state variable in you sketch that keeps track on if you want to make the guy move or not.

Try this example below. The boolean variable `play` control the state of the program a draw something only if it is set to true.

```auto
boolean play;

void setup() {
  play = true;
  frameRate(15);
}

void draw() {
  if (play) {
    background(random(255));
  }
}

void keyPressed() {
  play = !play;
}

```
