Damn, just finished the current content and I've gotta say, its instantly one of the greats. It seems like the development is taking quite some time, but considering the nearly ridiculous quality, that makes complete sense.
And I do mean quality, on all fronts. The artstyle is very well done, character design is great, but it's the writing and charm that make it a gem. Dialogue is well written, jokes (both in character and more physical/visual comedy) get consistent chuckles, and the story is actually quite intriguing. Elements like the ghost hunting segment, that take quite a bit of commitment to a certain tone, are also done really well, and add a lot to the games identity. The treatment of sexuality, identity and morality is also something that can really hamper my enjoyment of a vn, wether it is disrespectful or borderline sociopathic, as can be seen in a lot of adult vn's, but this game handles it really well. Obviously it differs for the slave route, I've been playing as mr nice guy mostly, but still its nice to get characters with actual moral convictions, who have their own wants and desires.
All in all, a 9/10, and only not a 10 because there's still so much I want to see. A gold star to the developer from me, and I'll be keeping my eye on this.
