Why isn the game compatible with Firefox?
Because it would not allow this kind of game to be written. Most of the game COULD have been written cross-platform, that is true. But there are things crucial to the game, such as disabling keystrokes, reassigning mouse buttons (right-click, scroll wheel, etc.) that would not have been possible on Firefox. That is mostly because Firefox wishes to be platform-independent, while IE has special tricks available for Windows users only. It would have been frustrating to get most of the game working on Firefox, only to find that certain important functions were not available. Q: “You made a game starring penguins, and made it incompatible with Linux. That is a cruel irony.” A: Yes, I know… not much I can do about it though. Perhaps someday a special “Mozilla-friendly” version could be released, though it would have to be redesigned for a different platform, as it were. See the last answer to understand why.
