I use to play roller coaster tycoon all the time! Really cool! When you scroll though, the edges aren't drawn. Wouldn't you be able to draw everything that would fit even partially?

There is no bounds in scrolling to the left. And when you click on the pull-back command, the units do slowly move back out of the playing area when at the edge of "map"

I beat it! J-M You have completed the game!!!

When I ever have setImage statements, they are where they only will be executed once upon such as an event. And i don't know i just use them.
