So far it is indeed just the introduction but it does seem to be rather decent.
It's only the prologue so far, but the premise is interesting and there's quite a few pages of well-written content!
Definitely worth watching for now.
If you find the description interesting at all, this is worth checking out. It has decent writing and an interesting few ideas. To me this is a game that seems well worth watching.
If you're looking for something with pretty pictures - or ugly pictures for that matter, keep looking. This isn't it (at least not yet).
If you're looking for a good story, though, this has the beginnings of one.
