this is an interesting concept.

The presentation still needs some work, especially the application where you can select and play the scenarioz. I thing that it should rather be a window based application, not full screen! A bit more like "steam" from valve..
those rolling screen changes are soo 1999 . Also those scenarioz need a good description!

the shooter tutorial is way too low quality, sorry. It might really scare away possible customers. The jumping part was really frustrating.

other than that, I'm already thinking about what mini scenario i might add. Hope that you can assemble a solid base of applications with the help of the community!
