Been musing about making my own VN but I think Ren'py would be a lot easier to use than Unity since you basically just drop everything into the corresponding folder. Not sure how that would change the visuals but I've seen incredible looking VN's made in Ren'py. Also, love Castoria's route so far but take as much time as you need on developing. Costs for drawing different poses and expressions along with the voice acting must cost an arm and a leg
(no pun intended)
