Not going to deal with Character traits. However the issues with how they shift as well as the 'Polls' changing the story, and what people see as inconsistent go to something that has been mentioned here A LOT. DS is not comfortable with or seems to have issues regarding the Incest aspect of the game.
I think some small changes in the game could make the story and character shifts run more smoothly/enjoyably (let us buy little gifts for the women, let us swim, have the Ladies be the focus of the Camera NOT Max, etc).
One issue that seems to show up in Games/VNs is the balance between storylines. The creator reaches a certain point where they have to focus on one path to provide a 'acceptable' amount of content, or try to balance progression for all. The problem is that people (including me) want a significant expansion in at least one part of the story each update. Don't really have a solution to that balance vs large increase problem, but thought I'd throw it into the mix.
Going to hide now before rotten Fruit and Eggs start flying my way.
Just a thought
