Now that I've spent some time playing Hiraeth (I just completed with Pocket last night), I wanted to post.
Hiraeth is dark, beautiful, surreal, and challenging.
It is abundantly clear that much time and care was put into the art, graphics, and environments; you'll also find clever, original use of the RPGMaker engine throughout.
If you're looking for a linear game that spoonfeeds you advice look elsewhere, but if you're up for a moderate challenge and wish to experience a journey through a subtly (though sometimes quite overtly) terrifying world with a spooky story you've found it!
