Completed Unnecessary hard game *Updated Again*

So here is the thing I sent this code to CSNorwood who helped me make the code shorter. So This game has now been re-written, re-worded, and re-structured with a lot and I mean a lot of help. I have asked and have been given permission to release this game again as I did not work on this alone and an agreement was made that he really does not care lol so the update is here and the download and been updated also. A massive thank you to CSNorwood for all his help.
