I don't know when the demo will be out.
The levels all look a bit "samey". In my mind, these are near enough the same screenshots you posted last time.
This is a platformer/puzzler type game, and like "Best Friends" which had similar look and feel, each level is very different, I guess you need to play the demo, but demo release is up to idigicon giving the nod, so I would imagine February for a demo
