Earlier this year, Microsoft revealed a new, easy-to-use game creation toolkit for amateur and wannabe game developers, as well as those just interested in making a fun game for their friends.

That toolkit, named Kodu, is now up and available on Xbox LIVE Marketplace for a 400 MS Points purchase, while a demo is also readily available for those wishing to give it a test spin.

Kodu promises to enable easy creation of simple games using their custom programming ‘language,’ which is all based on iconic imagery that you are able to place in flowchart diagram-esque configurations in order to apply properties and behaviours to pre-made (and user created) objects and environments, all carried out with your controller.

Once you’ve built your game, you’ll be able to share it with people on your Xbox 360 friends list, which is handy because you’re also able to create cooperative and multiplayer games. Lead Kodu Game Lab Programmer, Matthew MacLaurin enthused:

“As a programmer, I wanted to help create something that unlocked the magic of Xbox 360 in the same way that I was able to unlock my computer as a child and bring my imagination to life through games.

“We had such success with bringing ‘Kodu Game Lab’ into classrooms and after-school programs that we wanted to offer it to any wannabe programmer or creator through the Xbox LIVE Community Games Channel.”
