I love the look of the game and the intro was incredibly good.
Of course I decided to walk of the path into the void and that is still possible.
Collecting cats and solving the dreams was fun for a while, but when it came down to the last few it turned into running around looking for that missing puzzle piece. Especially looking for the last house took a few minutes. Perhaps you could make a minimap or have the leftover houses be more obvious.
Great demo, keep it up.
