This was a pretty good visual novel game. I rarely ever play these types of games, so I was surprised at how much I enjoyed it. One suggestion I'd make would be to have a way for the breast and ass expansion paths to intersect for a unique hourglass expansion path. I think I'd recommend having the option be after the full ass expansion path. Once her chest gets bigger, then she'll have to get new shirts which would look really sexy going with her leggings.
