I love the character designs! Bunny's eyes especially are absolutely stunning :o And I have a weakness for hats of the specific kind that you drew because they always remind me of one of my all-time favourite anime characters, Kuroudo Akabane from Get Backers xD The title screen is super attractive too!
Oh, and you taught me a new word: Haphephobia :D I had to look that one up! Now I'm wondering if my brother possibly has that because he really doesn't like being touched at all, not even for a hug from his big sister >.<
I haven't exhausted all the choices yet, so I don't know if they lead to a different ending to the one I got or not. I'm guessing something does going by the description on the game page :3

I always love me some post-credits gubbins :3
