I first saw the concept of single player rpgs of this type just a few days ago and was shopping around to see what would maybe work for me. There's a lot of neat systems and styles but when I saw this in particular something about it really caught my attention and imagination.
I don't have any experience to say what is or isn't missing in the file when you mentioned its in alpha but browsing through the document but I am having a great time trying to get stuff setup to have a go and finally feel really motivated to give things a go.
I hope you keep at it but I appreciate what you have posted none the less since its given me the really great gift of inspiration and motivation!!
