Progress with 2D game

I've finally made some progress with my Mario/2D game. I've now gotten him to collect coins. Before that was a serious problem for me but I now got Mario to eat the coins. I also add many sound effects that are actually from the original Mario game. I got the jumping noise, the ding for when Mario collects coins and I even made the game over music. What I am trying to do now is make a scoreboard. I am using one of Michael Kolling's videos on YouTube. CLICK HERE TO SEE THE LINK I USED. There is still more I want to do with the game. For example, I want to make text appear when the player beats or loses the game.

What the game looks like so far
