Yeah, it's my first game, having a lot of fun making it! Hex was definitely an inspiration for her design, as i find her looks charming, but i think Hinas personality makes her stand out.
As for other influences, hmmm...i can't really think of anything specific, just from a lot of different romance manga and anime.
Oh, and "My Pig Princess" is great! I love the art, story and pacing of the game, so i'm trying to match its quality.
I have a lot of things planned for the future of this game, so i hope people stick around to see it unfold!
