One of the primary inspirations I used for this game was Monster Girl Quest, which is a personal favorite of mine. That game is significantly more linear than mine but both are heavily inspired by the visual novel style of storytelling. This is just the demo with a single area, the tutorial section basically, before the game starts opening up into more areas with more characters and interactions.
I know it's not the most robust game in terms of the combat system. My focus for the game is more in the art and the writing. I'm sorry it couldn't be the RPG experience you were hoping for but this game is more of a visual novel RPG than an open-world adventure RPG.
