Today I tested the game with Firefox. It did not work. However I kept at the code until it worked in Firefox. The colors actually look better in Firefox than in Internet Explorer. I also made the message box a horizontally scrolling one.
A major addition I put in tonight was the Big Boss on the bottom level. Well he is actually not that big. He is a giant beetle. But his has a lot of hit points, and can do as much damage as you.
