This is worth playing for some nice scenes between the Mum and MC, but other than that, not a lot going for it.
The Good
The Mum is a sexy MILF, and has some anal/sub scenes with the MC that are pretty hot. She also does not waste any time jumping him, though it doesn't really explain why. Very nice that the Mum is the first sexual partner, as incest games that hold the Mum as some Holy Grail, and make you wait years to bone her, are very irritating. Some of the character design and renders are pretty solid, some are pretty horrible, the render quality is all over the map. Regular updates, and decent amount of lewd scenes so far, though some are pretty poor.
The Not So Good
Bare bones story at best, it doesn't even really hold the lewd scenes together, no real character or story progression, and the events seem to jump back and forth in time, over the course of the days.
MC looks like a teenage zombie, or maybe one of those sparkly vampires, without the sparkles. Pretty hard to look at most of the time.
One of the Sister is hot, the other looks like an ugly boy, and even though it's called a family affair, there is no lewd content with them yet, aside from some dreams that don't count. Not even some building to lewd content, they don't even seem to notice the MC exists most of the time. This game has been in Dev for a while, and they should have some sexy time by now.
Dialogue is pretty rough, MCs personality is pretty much a dial tone, and none of the choices seem to matter much aside from choosing which content you want to see.
Full on 50% of the lewd scenes are with Trans characters, which seems fine at first, but there is only 2 and there are a lot of non-trans characters that get little or no action as a result of this imbalance. The Dev also seems to have a very specific way he wants the Trans characters to be treated, and if the MC doesn't conform he seems to get punished, and eventually rejected. this is very strange, and not a good way to handle these characters in my opinion.
Animations are not very good, not varied much at all, and are way too short.
Overall has some nice content with the Mum, and had some real potential. Not enough story to give more than 2 stars, and even if you are open to Trans content it is not handled very well. I think this game can be improved in many ways, but it's probably better to start fresh.
