I´ll write this review for those like me who really enjoyed obasans saga and wanted something similar.
Sadly this game tries to go for a bit of everything without focusing much on anything... well, maybe a bit too much on NTR, this along with a half-ass focus on combat, a non-linear story and reduced number of milfs hurts the game for those who wanted something more similar to obasans saga, does it make it a bad game, not necessarily, the art is good and there can be something you enjoy in it but not much else... unless you are really into NTR then you´ll like this even more.
The H scenes can get a bit repetitive since some are reused poses with different clothes or a few changes in the dialogue, and a major problem is the Hana scenes, which are unavoidable NTR, she has the most scenes and half of them are NTR.
In the end, I feel the author tried to add a bit of everything for everyone, but in the process he added a bit too much NTR and too little of what made the first game great.
