Aimma, that is not true at all. Most games on Kong work cross-platform (Linux, Mac, Windows). That also holds true for Java games. Only problems that I (Linux System) often have is with games that need the Unity Player which doesn't seem to work properly on my system. But as far as I know even that works on a Mac.
"Little one, you have so much to learn. Be patient." How is that supposed to help?! I lost my balloon and I'm stuck. Patience has nothing to do with that.
