Let me start by saying that I really like this game a lot.
I love all three ladies in the family, they each have their own strengths going for them.
Auntie has the curves like no other, I mean she is fucking thicc, but even if her ass is gigantic, it works fine for me.
Elder daughter is like a younger version of mommy, but she is clearly more willing to act on her feelings for the MC, even if she denies them verbally for a very long time. We get to pop her cherry, and so far she is the only one we manage to have real sex with.
The younger daughter really has a Lolita charm to her and while yes, she is obnoxious and can be annoying, she is the only one honest about how much she is into the MC.
Visually, the girls look absolutely fantastic, if you like your ladies with a ton of curves. Nothing against the laws of physics, but both the aunt and the elder daughter are voluptous af. The younger daughter has nice curves as well, but does have a different body type, which is great because three ladies who look like they are just the same model in different ages, wouldn't be that great.
The reason why I can't give the game more than four stars is that it definitely has many flaws and even if like a game a lot, I still have to take them into account when it comes to rating the game. (hint: this is how reviews work, listing all the problems and still giving a game five stars is the worst)
Okay, problems not in order of importance, just as they come to mind.
1. At the beginning, auntie lets you do many things, and then she changes her mind, and then she lets you do many things and changes her mind... this is no mistake, she really does this several times. I think the idea was to get at least a bit of action with her, so people can see what's coming, but at the same time keep up the teasing. The problem is, it is done so radically, it just seems forced and repetitive, to a lesser extent that is also true for the elder daughter. There is a fine line between teasing in a way it keeps you all horny for the girl and being tedious and a bit annoying, and sadly Heart Problems veers into the latter from time to time.
2. The writing is pretty riddled with errors and if those are too numerous it tends to get me a little out of the game. Otherwise, it is perfectly fine, but I would love if someone with editorial skills could go over the whole game once and remove those mistakes and maybe do a one over of the writing as well.
3. The younger daughter is so into the MC and the MC already has zero problems starting something with the older daughter, while going after her mom as well, so what is the fucking problem with the younger daughter?
She is younger, yes, but obviously she is not a pre-teen or anything, she knows about sex, and she is infatuated with the MC and his dick, so just fucking stop leading her on and give her what she wants.
4. The story is in many ways just the usual incest game story, that is not a problem per se, because it is done well and has glorious models, but it kind of feels wrong to not let it go into the rating in some way.
TL, DR would be, three frigging hot ladies, a lot of teasing, but really sexy for most of it, writing is fine, but could be better, grammar and spelling could and should improve, but it's worth your time if you are into thicc ladies, and aunt/cousin incest.
