That sounds very interesting, since I am also interested in machine learning. Of course I would love to share the source-code with you. Just send a mail to gerhard[dot]wonner[at]runtothestairs[dot]com and I will send you a zip-file with the source-code of v0.9.
Please share your results with me. Maybe your efforts may lead to more interesting AI for RunToTheStairs one day.
By the way: RunToTheStairs is still in active development. I am currently coding a server sided backend. This takes a while since I do not have much time and have to learn everything from scratch. But I think it is worth the effort since it will allow to provide a lot of interesting statistics.
