Update 1.3.1

Just a fix because I realized that I forgot to put the end on level 10 (luckily no one beat it so no one knew). I also added a bit more to level 5 because I thought it was too easy.  Someone has recently contacted me about a soundtrack for the game, so hopefully we will have one in the future. Also, someone has gotten to level 10, but no one has beaten it yet, so keep on going if you want to be the first.
