The story is concise, between the son and mother there's a lot of emphasis about kindness and care, for me it feels really genuine and personal. I prefer these kind of stories with few characters, which explained motive and background. Frankly there's no complex and convoluted story just simple pent up impulses build up over the years.
The renders looks really good, each still image shows significant emotion. Enough animated scenes for lewd scenes. I'm really glad that for each encounter there's kink of choice.
In my humble opinion, since the game is short, it wouldn't be too much work to add a few sound effects to the lewd scenes, it would elevate the level of immersion to a new ground. I really encourage the the developer to take a look at Summer Heat where, subtle small sound effects employed really well.
I know, i shouldn't compare to other games in the review, but somehow i feel resemblance with Measuring My Cum, what i also found really impressive work.
