Let's talk about what is good about the game first. This dev produces excellent work when it comes to the visual aspect of his games and he does well making his characters seem to come alive visually as they speak.
It is difficult to discuss the plot of a 0.1 game so we will just have to see how that unfolds. The basic story of "not" related people living in the same house and getting it on with each other is a well-worn path so there is little in the way of surprises. We have a mother figure, an aunt figure, and the usual collection of "not" siblings and "not" relatives - the rebel and the quiet one etc,
The dialogue is adequately handled although hardly inspired and the 0.1 trundles to its completion with more of a sigh than a full-throated roar.
All in all, a reasonably competent, although average introduction with a couple of paths set up to follow.
If the game is updated regularly, the plot may start to develop into something more than the usual peek into bedrooms and bathrooms trope and become something more than simple eye-candy. In fairness, the renders are very well done so let's hope the dev can apply that same eye for quality to his dialogue and plot development and manage to keep to a reasonable update schedule.
If so I will be happy to adjust my star rating, but for now, because of the lack of originality, a 3/5 rating is a reasonable level to peg this new game at.
