To be honest, there's a lot of aspects that are not good, but there's a lot of potential, and a lot that is already more than good enough.
The fondling mechanics and trying to get a blowjob to happen are both terrible.
Not being able to fully control our main character from a different angle than POV is problematic, especially for the aforementioned blowjob.
The girls that are randomly generated are for the most part really ugly.
The girls are way too bloody sensitive, and take too long to seduce.
The autosex is obnoxious.
Only 6 hairstyles in the whole bunch are worth using, the others are ugly for various reasons or entirely broken/defy gravity.
Most hairstyles that aren't parted in the middle have hair straight cut, and no distinction between the length of the front and the back, so you end up with either straight bangs, curvy straight bangs, hair that is too short in front, or nothing.
There's nothing in the way of bangs that aren't straight down with no uniqueness and parted bangs.
Since it clearly uses a similar system for hair as VAM, if you could import your own, it'd be ideal.
Now, a large majority of the problems are fixed by the MonkeyMod.
I wouldn't play it without the Monkey Mod, but with it, you can make some fairly nice looking women, and you can control the aspects of the game that are inconvenient.
I'm very happy that chin clefts actually get some much deserved recognition.
I'm not happy about how needlessly high poly the model seems to be.
Being able to have a lower poly version of the model, like we have for the hair, would probably be ideal for optimisations' sake.
Like, half the polygon count at least, could be achieved without degrading visual integrity that much if at all, especially in areas like the hands and feet.
The piston action is pretty good for the most part, minus initially getting it in.
