IMHO, most of porngames containing ntr are garbage, unworthy of anyone's attention.
This is a rare case when it’s done with soul, even though it looks simple.
The efforts of the author are noticeable, even in the first version that I played a few months ago I noticed only one minor bug (now fixed).
I usually check all the branches in games, including fetish ones (even if it's definitely not my cup of tea), and, speaking of this game, there is not too much "vanilla" content here yet (if we could consider "stepincest" as the very thing), but there is a lot of corruption and NTR content. For me, the small minus is that “vanilla” path still has unskippable or non-rejectable ntr.
I'm not a native speaker of English and even not so proficient in English at all, but in many of the games I played here the game conversation tree in English looked repulsively incomprehensive for me, well it was impossible to understand the meaning, despite it wasn't not some kind of an idiom or slang. It's even worse when the dialogue consisted half of inarticulate sounds like "GHHYYA", "HYAA", "WARGHH', "MGNOM" of whatever. I didn’t notice this bvllsheeet in this game, there were some obvious speech errors, but the meaning of the text was translucant and that’s nice. But speechlines of the stepmother are some kind of strange, she seems to be very, very stupid (the dumbest of all the game characters), however, her actions are naive, so I decided that this was done this way by the author’s intention, i.e. this is her personality, not a flaw. By the way, I noticed the author also “spare” her unlike stepsisters, i.e. there is actually less "hardcore" content with her at the current version of the game. Perhaps this is also the author’s idea: probably in the end the main male character will be happy with his "a little corrupted" stepmother, while he doesn't really care about the sisters.
New versions of the game are regularly released according to schedule (even free versions are usually released as planned). So it has not yet been observed that the author deceives subscribers on Patreon (or a similar platform), unlike many other developers.
Another small defect is a sorta primitive combat system, if I could say "Harem Wars" is kinda similar game to "The Last Hero's Darkest Quest", in HW the combat system looks the way better (however, even there there is muff, after a certain phase of game you've got a fairy with an imbalanced skill, making literally every battle a secure win )
I'd give the game solid 8/10. Can't post it in reviews, because my comment does not meet the requirements of Reviewing Rules.
