Usually, I don't post reviews, because most people don't really care and either play, due to them being fun or for pressure release. But I couldn't skip the "classic" to discuss about, due to courageous concepts other games pretty much inherited from.
Beginning with the usual, positive things:
+Setting up the mainstream VNs and other clones around behind the scenes mom-son sexual relationship, foundation. Summertime Saga is definitely the grandfather, but DoD is what encouraged devs to trial and error this kink. Up until that point, most incest games were developed by asian studios, very much unknown to other continents.
+Renders. For what it's worth back then, the characters looked great.
The flaws:
-Character development and story felt very artificial and forced. I comprehend this whole fetish can't get more natural, but domination as a main theme really put me off, because MC's actions felt like rape and out of the benefits for himself, rather than to aid his crush and other lovers. There was no fruitful chemistry, convincing that these justifiable actions were for the greater good and not something, because the MC was horny all the time.
-Underwhelming sex scenes. After the long culmination, the end reward was poorly planned out. As if the dev just didn't care anymore for what was worth and dived in just to complete it in time.
-Lack of audio immersion. Applying simple, copyright free music is definitely welcoming, but sex SFX, in my opinion, should've been implemented. Simple moans, groans, swallowing could've offered more immersion, instead of staring at static images.
To probably sum all things up, if you, the reader cease to believe any other Ren'Py based VNs exist, this is a must try. It was gold in it's time. Contrarily, there are better games to play that offer better immersion and somewhat more convincing chemistry between characters like, Dual Family, The Wish, Summertime Saga and countless more.
