Flappy Bird Coding

Today I was learning how to code flappy bird. I made the background snow and the player Santa so it looks like a christmas scene. I dragged special buttons together like a puzzle and it codes it to do what it says.
I found it easy to make it make sounds.
I found it tricky to make it end the game when you hit the ground or obstacles.
My digital learning object shows that I know how to code a game.
Here is the link to game.
