I don't know why. I don't have any errors, but my snake doesn't show up when I start the game. I can see my apple, but no snake. I managed to pass the last few parts, it was saying I had everything right and I could move to the next step, but everytime I passed, I still wasn't able to get my snake to show up in the screen. My snake was showing up in the part where we created the draw method, but as I advanced further into this, it stopped drawing my snake and I have no idea why ?
