Hi Sandpixie. Thanks for your interests. We have done a whole improvement on the GUI design, character sprites, and a whole route one is completed. There are some arts still being done, and other routes still being working on. There would be a blog update on the progress soon. Cheers! :D
It is for the final product. But along the way when all the demo part that have been changed are finalized, it is possible to make a snip and turn it into another version of demo. However, due to a very tight schedule we have, it's might ended up come out after the final product itself.
