There now is an English Demo! Please try it out if you think this could be your cup of tea! If you have any feedback you can contact either [url=contact@playism-games.com]Playism[/url] or Novectacle. Even though they're a Japanese doujin circle, they've always been happy to answer my questions in English - they're very friendly and great people to talk to, so please don't be afraid to let them know what you think of their game!
Hello! I've seen a few people posting about projects on Kickstarter or translations of commercial games not affiliated with Hanakogames, so I thought I'd bring this to your attention:

Playism EN Wants to Know If They Should Localize The House in Fata Morgana
Doujin Delights ? Playism Tease Three New Localizations
Should we localize The House in Fata Morgana?
As you can see, Novectacle started moving to try and have their game localised; I've tried their demo with the help of a translation tool and I really want to be able to enjoy it in a language I can understand. As you can see in the links above, the art is stunning, and from what I could experience, the atmosphere is very interesting and quite different from what most VNs offer. Eerie, gothic, probably a bit horror going on with the story. Before you go and try the demo I'll tell you there is violence and gore, so if it's not your cup of tea or you're not allowed to see that kind of stuff due to your age, you should hold off from downloading it.
If you're interested in this and you think you'd like to buy it if it were translated to English, please comment on Playism's post or send them a mail letting them know you're interested! Post on Facebook! Post on deviantArt! Post on Twitter! Post everywhere you can think of so we can get lots of people interested and we can enjoy this in English!
There's a video as well, but please be aware there are a couple of scenes with blood in them. Again, if that's absolutely not your cup of tea, I'd advise to steer clear of it, though they're not incredibly gory.
