Not my cup of tea... and yet...
I honestly thought it was really well done. Considering all the slapped together madness flashes ... this really stands out. Not only in the animation, but the thought behind it. It wasn't one of those "random click everywhere" point and clicks ... there was a cool logic behind it.
If the rest is anything like this demo ... I think you've got a very good game on your hands.
Add some "side-quest" stuff, some red-herrings, and medals if you can, and you've got gold. :)
