Man... I was pretty sure this game wasn't that bad. Oh well, Thanks for y'all honest opinion.
Demo to demolition!
Gave it a go, I can see where you wanted to go with the story, but it's all over the place, and people seem to act like caricatures of their roles that someone far too young to be playing this game would come up with. It's made all that more awkward with the robot-voices you have reading the text. Dropping those voices would be an improvement.
Having the preview image of some dude groping the female love interest isn't going to help you, either. If you wanted to include that scene in the main post, should have been the follow-up where she pushes him away, at least. The scene could have also just never happened, and just been Chicha spying on her mother with the guy.
The entire intro sequence with the twins trying to interrupt their father is so nonsensical and confusing. Charmin is trying to get his sister to call to their very naked, very involved antics, and you never mention why until a few scenes after. Their reasoning to talk to him is something that can absolutely wait until he's in a better mood and properly dressed. So the entire situation is completely avoidable.
Mother being an adulterous bitch was fine, as her husband isn't really much of one. Leave her to her own shit, and keep her boyfriend's hands away from the twins. You don't have an NTR tag anywhere on this thing, and that's too polarizing of a situation to have it be a thing.
That mini-game deal was unnecessary. It's more confusing than most of the other stuff about this thing. May want to try working on the script before moving on. People can usually ignore some quality in favor of a better story.
If, however, you *do* intend on having that black guy on Chicha, I warn you to slap an NTR tag on this thing immediately.
One should absolutely NEVER hide/bait'n'switch/smuggle or any other way try to mask NTR from your tags. It's too polarizing to not include in your list if it's in your game. People who look for it, may not even see it, which shrinks the audience. People who hate it are going to overlook a lot of the signs of it being a new dev, give the game a try, and react very badly to not being warned.
