Thought I'd throw my two scents in here:
This is my favorite game in F95 right now. Very addictive and fun as the author has taken his time with the mechanics of relationships, sex, and other attributes to be able to determine game play.
Right now in my opinion, the only shortcomings are:
1 - Polyamory (doesn't work at all) Even if you have this attribute, none of the NPC's in the game care as if you enter a relationship with another NPC that has Polyamory as well, they will still give you ultimatums to leave the other NPC.
2 - When staying loyal and celibate to your GF, you will take an 'Unfaithful Hit' if you go out on any date. Even if you do not do anything on that date.(At end of date you leave. No kissing or hugging) This needs to be corrected by the Developer.
3 - If you want to be together with a single person, do not respond to any flirts, date requests, or being flashed cause if you do you'll get hit with an Is Unfaithful as well. This needs to be corrected by the Dev as well. Test should be when you go out on a Date, do you kiss and take it further while being involved with another. Not just because you went out. In real life, friends go out with other people without being labeled as a cheater or unfaithful just because they went out with a friend.
I have some other short falls, but this is already too long for me to type out.
Again, this is a great game with great mechanics, graphics, and modifiable through configuration files. In my opinion, the Developer has truly though of everything. Now just needs some tweaking.
