That's damn impressive, I wasn't expecting this at all! For a demo it was plenty: few characters were introduced, relationships established, character traits were shown, the past played a roll etc. The art really as good as the other guy mentioned, the tunes are catchy, and plot wise so far so great.
The entire concept of such a thing existing, probably just like that... Weird, but honestly? Fantastic!
When can we expect the first build?? I'm next in line to give 5 stars haha – review comes later though
*SPOILER*
I don't expect it, yet do hope Mat didn't shrink down to the size of a cockroach. (pun intended i guess)
