Off to a great start, but, the chapter is extremely short - 30 minutes or so.
Very little choices, but the writing is pretty good for this kind of game.
I would strongly recommend that each chapter to be longer though, even if you release fast enough, 30 minutes of playtime is simply way too short.
Good luck regardless, this is really starting very well.
Please, do not add futa or interracial though, everyone else already does it, a breath of fresh air would be rather nice.
