I didn't know that Greenfoot can draw outlined text. Are you actually using images, or is the text really drawn in code? Also, Greenfoot doesn't have a default font; Java does. And Java's default font in Windows is not the same as the one in Linux. I am also using the open source openJDK instead of the standard JRE.

Where's that skip button... I haven't really got the graphics driver working on my computer, causing this game to go around 4 FPS, the intro takes almost half an hour...
