This game does have it strange problems. First up, the side girls and 1 main girl called Emily. If you haven't played this game before don't click the spoilers.
ALL if the side girls should have also been main girls to the MC, no two ways about that fact.
The MC seems to start off okay, but does he develop strange behavior problems about mid game.
It's as if someone took over the writing of the game and changed the MC to become a man-child idiot.
For me there is a main side character and it isn't Samantha even though she is a side character.
That right there shows me that the dev got lost in his own game writing, because it does focus less on the main girl as time goes on (episodic time).
I am honestly trying to like this game, but it is so difficult. There needs to be some major changes, because what he has written so far is disjointed in my opinion. The MC needs a major overhaul so he is a likeable character and not a 10 year old mind inside and adult body. Then we have how long he takes to get an update out. This latest update has taken more than a year, and there is very little to show for it. If the dev want's to abandon this work, he should just tell us. I think he knows he has made a faux pas with this game.
So here is what I would do, if your going to rewrite the story.
1. Make the MC a normal likeable guy, not some manchild with a brain the size of a walnut, I am serious. If he is badly written it doesn't matter how good the rest of the game is, he is the focal point, everything happens around him, you take the role of the MC from his perspective.
2. Drop the side girls and make them all main girls along with Emily. Remove the points, but if you keep them they need to be universal across all main girls, which also means you have to write a back story for each of them, they would be wooden otherwise and no way to relate to them.
3. Make the story flow more, it feels completely disjointed.
You have it in you to change this game into something a lot better, something that makes sense, and a mc who is nothing short of a joke that one that is not funny (The MC needs some TLC to his character, the way he speaks and behaves and reacts and is really likeable. Try to add some realism into him without making him a borefest.
