Stuck for a while

I haven't been posting for a while now because I've been kind of stuck.  I've tried to do the chapters but they are very challenging for me.  I have also been stuck on my mario game I've been trying to make the game end once the actor reaches a flag but that hasn't really worked. I also am trying to add a score board to the world. The last time I tried I had some difficulties but im ready to try again. My latest contribution was I added many sounds to the game from the original mario game. I also added a dragon as an enemy. I am also thinking about having mario being able to shoot the dragons and if he succeeds he gets more point. And I may have a coin that is worth more then the others.
