Last milestone completed

Completed the project. I wanted to replace the player with a penguin, but it didn't fit the maze, so I kept it as an '>'.
It shows where you begin and where you need to go to finish, and each game is a different maze. I thought this was very difficult and i needed to learn how to make a maze, I was not prepared for that.
