BTW, I will be adding pedestrians to the sides if the street so that you cannot go on the sides. WARNING: Running people over may be gory... lol

Yes, I was planning that as you can see with the jumping class but was unsure how to implement it and your comment reminded me of the setImage() function; the only problem is that I don't know a way of making it so the runner is invulnerable whilst jumping can you think of a way. I posted it on here to get peoples opinions on how it could be improved, thanks for the input :)

This is really good but in real life if the marble was to hit another straight on wouldn't it bounce straight back the way it came? Just a suggestion. :)
