Congratulations, that's excellent! I'll have to show this to my daughter. She wants to make her own Hello Kitty game since she's been watching her older brother (8) making games on Scratch :) Its an excellent platform for learning the basics of programming. I was worried that my son wouldn't have the patience to work with Scratch since he sees what's on Wii and XBox and that has set his expectation level. But fortunately he's become very excited by Scratch and can build games with very little or no guidance from me now, w00t!
Thanks. I was expecting my daughter to get bored quickly as well. But having watched her, it strikes me as a software version of Lego - you'll never create a toy/game as good as one you could buy in the shops, but the real fun is the fact that you can create pretty much anything your imagination can come up with.
