The second one will say, “Start Game!”. Under Appearances, set the font color to #FFFFFF.

The final one will say, “Exit Program”. Under Appearances, set the font color to #FFFFFF.

Set these on the screen evenly spaced apart in the middle going down the screen.

Create two new pages. One will be named “Gameplay”. The second will be named “Selection”. Set the background color of both pages to #000000.
On the Gameplay Page, create two text displays and one rectangle.

Drag one text display into the top center of the page. Under Appearances, set the font color to #FFFFFF.

while(tag.read("Game ON")){
  var currPoint = tag.read("Points"); // saves the current points
  var chance = Math.floor( Math.random() * (100 - 1 + 1)) + 1; // random num generator
  tag.write("clicked", 0); // resets click status
  thread.msleep(100);
  if(chance > 50){ // 50/50 chance of being green or red
    tag.write("Color", "#00FF00");
  }
  else{
    tag.write("Color", "#FF0000");
  }
  thread.msleep(tag.read("sleepTime"));
  if(tag.read("Points") > currPoint){ // if the user gets a point
    tag.write("level", tag.read("Points") + 1); // increases the level
    thread.msleep(100);
    if(tag.read("sleepTime") > 250) // as long as sleep is not below 250 ms
      tag.write("sleepTime", tag.read("default_sleep") - (tag.read("Points") * 20)); // reduce it by 20 for every point
    thread.msleep(100);
  }

  }
  if(tag.read("Color") == "#00FF00")
  {
    tag.write("Points", tag.read("Points") + 1); // gain a point if green

Click Tools > Launch Simulator to launch the Canvas Simulator.

Click on "Start Game!". This will open up the difficulty selection screen. Select any difficulty. This will then open up the gameplay screen.

Click on the box when it turns green. The text at the top should increment the number of times you click the box. This will also cause the level to increase and the sleepTime tag to decrease. Click exit whenever the user is ready to move on.
