Well, I played your demo and here's my thoughts. So far, you have crafted a fascinating story that grips the reader from the start, along with some great characters. I'm a huge fan in particular of Archie. He's just so wonderfully eccentric. (or possibly a robot? xD)
My only complaint was when, at the end, Perry decides to go home, you don't really get directions or a hint at which house is his. Otherwise, everything played well and really set up the story for more. I'm actually looking forward to the full game.
