Damn. This is impressive, yes, but when I read "RPG" I was expecting something with a Final Fantasy-sized plot; as a developer who is also a writer, I was intrigued about the idea of developing an interactive story within such a short timespan--something similar to NaNoWriMo, but producing a game design document rather than a book as output.
This was more RPG mechanic rather than RPG. I still find that interesting, though, as the system I used to make RPGs in high school - RM2K, which is still out there - had the mechanics prebuilt and let you focus on detail. This game seemed to be quite the opposite.
