Just got this one today. Played the demo, loved it, so it was an easy choice. The visuals, although not immediately jaw-dropping, are still lovely and look like something right out of a Studio Ghibli film. The watercolour style has been implemented very nicely. Gameplay is fun as well, with intuitive controls and plenty of opportunity for strategical play.
I'll give this one a bit more playtime before giving a final verdict, but so far, so good.
