One Word - Disappointing.
Let's start with the bad.
The game started out great giving you a nice introduction to the characters, the household dynamic, the desire and love system, special events and some instructions about countering said events right before falling flat on its face.
Within 5 minutes of those instructions explaining how you can purchase condoms and use them to have sex with your partner in order to counter the advances of the unwanted house guest, you come to find that whatever choices you made on days 1-2 basically lock you into a generic story with a single path.
It may occasionally offer what looks like a choice but more often than not once you're on a path you're stuck on that path till the end, which makes all those instructions, in-game items i'e condoms and the desire/lust system a complete waste of time.
They don't do anything except give you this fake perception that you are somehow in control of the story.
Advice regarding the bad.
It's fine to have a game that gives you just a few choices to direct the story what bugs me is you have missed the opportunity to make what could have been a very enjoyable player experience.
A game where every choice matters, a game where you could change the direction of the story at any point as long as you haven't hit that point of no return assuming the point of no return doesn't occur on day 2 of course.
Where do you go from here? In your position, I would make 1 of 2 choices.
1. go back and remove all the dialogue and stuff in regards to giving the player real choice that matters and turn the game into VN.
Hell, you could even port it to renpy and remove the need to walk around the house as it's also pointless.
2. go back and rebuild parts of the game so that system actually matters, break away from this single choice dictates the story going forward approach and try to get creative with how the mechanics could work if the love and desire values were fluctuating back and forth throughout story progress.
This will also increase the replayability of the content tenfold as it will leave room for players to experiment.
- What happens if I just ignore the girl?
- What happens if sleep with her every chance I get but don't actively block the an-tag scenes with her?
- What happens if let them bang for half the game and then make a heroic comeback in the 2nd half?
Let's move on to the good.
Overall the premise of the story might have been done before but it's a fan favorite and people love a game with choice.
The renders are pretty good, the scenes/animations are enjoyable, the art style is nice and the main girl is attractive you have everything you need in this department.
The writing isn't bad either, some parts dip into the realm of being unrealistic where the MC is dumb and just accepts whatever lies they feed him but it's a porn game so it's to be expected.
In general, whatever you decide to do going forward I think the game will be relatively enjoyable and worth at least 1 play-through of each path.
Conclusion
For those that haven't played this title yet, give it a try you may form the same or very different opinions from mine and you would be doing yourself an injustice not to give this game its fair chance.
That being said although I'm disappointed by the direction the game currently takes I think you're doing a pretty good job so keep up the great work.
