It’s called CodeCombat, and it’s available now!

I was inspired by my own experience learning programming. I started out as a kid playing around with BASIC on my dad’s old PCjr (which had no graphics mode). Then I moved onto QBasic and Visual Basic 3.0 at school, where we wrote little programs that would print “Hello World” or draw little ASCII art pictures of our initials when you clicked them
