c# Turtle recursive function adding 1 angle

I saw this video on TikTok and wanted to code it myself using c# Turtle, and I do know it should be easy but whatever I'm doing doesn't work like the video does. Here's what I tried:

 Turtle t = new Turtle();
 t.TailDown();
 for (int i=0; i<1440; i++)
 {
   t.MoveForward(5);
   System.Threading.Thread.Sleep(2);
   t.TurnRight(i);
 }

And it just does 2 and then repeats itself, I might just be dumb but also tried messing with some if statements but still couldn't get it to work like I wanted..
