I like the game, but it has a few bugs. For example once they got the poly relationship, the scores of GirlX.LikeGirl is reset, and you need to grind them again for harem acceptance.
Other bug, if you ask girls to fool around another (threesome, but with no intervention of your part) you can indefinitely create a loop that consume no time and energy of girls licking cum from each other even if they don't have cum on them, and grind a +13 each time on the GirlX.LikeGirl score. Mechanics are a bit fishy to be fair and not very clear...
