A bit worried there are only two reviews that aren't really reviews (one asks a game question) and one discussion. It looks like a pretty standard puzzle game with some atmosphere.

I noticed in the trailer the princess from China and another female figure were dressed in Manchurian robes, who did not occupy China until after year 1644. Is that a minor oversight?

I'm getting pretty low FPS, even the mouse doesn't move smoothly. Is there any way to fix this? Maybe turn on a windowed mode or something? Is anyone experiencing anything similar?

Are some achievements planned?

I ever loved the work from Pierre Estève. Is there some way for the soundtrack to be released or is there a site where his work, including form older games, are available?
