The same problem like in "Unohana's Horny Xmas" ... by the permanent changes between spoil her, look at the pleasure meter and watch out for Santa, no real gameplay feature.
Please tell us, how do you think, anybody can enjoy that ? If you would make the achieved status constant, it would be okay. But so, nobody has fun with such kind of "games".
Some challenges and what to do before sex is absolutely okay, unfortunately the most player don't will have patience, to come at this goal. But, okay, - positives and negatives about these game.
Well, good that she is excellent drawing, and also the fun comes up a little bit, but, not really.
2 stars for the 50/50 work ... please, make a decision what you want ! Too much "work" and things, who are not important, not necessary do kill the rest from every gameplay, sorry, but, a fact.
