At first it's really weird until you realize that this is a "patreon compliant" version and you need a patch to get back to the real wording (half sister etc.). 

Then the game is quite interesting with little choices but okay.

From the vacations moment things become talkative. A lot. I don't mind a bit of plot but here, since the setting is unrealistic, it becomes boring.

Then there is the "granny" which i don't know if she will or not become part of the harem (i personaly would hope not because the harem is becoming gigantic and it stops being fun to have too much relationships).

Another thing is that the girls work in little circles which scarcely interlaps.

It feels a bit interesting, but mostly repetitive.

The character's are not bad, but there is not very much differences: aunt and mom are basically the same with a little variation in height and breast, little sisters are basically the same with one and cat features, the others not.

Sex scenes are uninspired and two-three frames long.

Some "outside of the family" characters bring diversity and are the most interesting (especialy Tanja and Fiona, but Yvonne is not bad).

Backgrounds are very poor. It isn't a problem until chapter 3 where the repetition becomes so that you pay attention to the visual other than the girls.

As for the personalities: do not look for. All girls are okay for a harem from first glance. You do not need to work, there is no discussion about it and it never will be evoked other than "who sleeps with him today?". It's quite not unusual but even in other harem games, the question arise sometimes before the situation is accepted.

Besides the "how to play" is weird: you download v21 but it asks you play v14 for the 9 first chapters then load your save...

So in short: a good VN but not a polished one as of this version.
