Damn,you're planning big on this game and I respect it, the art style is really unique and from where you're going with the updates, this game will be both good on arts AND content, prob slow on updates due to where you're aiming at but quality over quantity!
Edit: good thing you didn't plan adding a yandere into this, a yandere and a harem isn't a great pair at all, not for the girls and the guy..
