My first game ever

[le ly]

I'm 13 and was wondering if you could give me some tips on my code or what to add?

float score;

int x;

int y;

float v;

PImage img;

PImage imgg;

float scoreR = 20;

void setup() {

  size(500, 500);

  score = 0;

  x = 200;

  y = 100;

  v = 1;

  img = loadImage("banana.jpg");

  imgg = loadImage("background.jpg");

}

void draw() {

  background(255);

  image(imgg, 0, 0, width, height);

  image(img, x-25, y-20, 150, 150);

  fill(0, 0, 255);

  textSize(20);

  text(score, 20, 20);

  text("upgrades", 350, 20);

  fill(0, 255, 0);

  text("20", 375, 40);

  text("80", 375, 60);

  text("320", 375, 80);

  text("1280", 375, 100);

  text("10240", 375, 120);

  text("81920", 375, 140);

  if (score>20) {

     if (score>scoreR) {

    scoreR = scoreR * 4;

    v=v*2;

    }  

    if (score>scoreR) {

    scoreR = scoreR * 4;

    v=v*2;

    }  

    if (score>scoreR) {

    scoreR = scoreR * 4;

    v=v*2;

    }  

    if (score>scoreR) {

    scoreR = scoreR * 4;

    v=v*2;

    }  

    if (score>scoreR) {

    scoreR = scoreR * 4;

    v=v*2;

    }  

    if (score>scoreR) {

    scoreR = scoreR * 4;

    v=v*2;

    }  

  }

 

    

}

void sap () {

  score = score+v;

}

void mouseReleased() {

  if (mouseY>y && mouseX>x && mouseY<y+100 && mouseX<x+100) {

    sap();

  }

}
