good game, just try to include a way to have harem and for girls to join when the MC is having "activity", based on lewdness, threesome love level... for the harem, it could be nice to propose a woman to join.
after playing a couple of hours, I have noticed some issues that should be corrected for the next update : all the activities are recorded, and the more you play, the more is recorded. if you add the fact that the other characters' activities are also recorded, and that you have more and more character in the game, at one point, your system is not able to absorb the load. the save file is 500ko at the beginning, it's now more than 13 Mo... I am not sur that recording everything is necessary or usefull. Some internal cleanup should be set in place. another point, differences between polyamor and monogamy are obvious, but not the fact if it's for the considered character or something else. You could introduce something simplier like jealous?
