Well, this is @Onater's fault I made this. He said "You never seem to make games anymore!" So I made this. I was looking through my old unshared 1.4 projects, when I found this game. It was full of bugs, and I'm guessing that's why I abandoned it. When I found it I thought the idea was cool so I made a new version. It has MUCH better graphics, programming, and score system.
