That would be down to our amazingly talented artist, LazyPolarBear :3 It was a bit of a funny situation with the UI because she made all of the assets with Ren'Py UI in mind since that's what we were going to make the game with, but we wound up using Naninovel in the end, so I sadly wasn't able to implement all of her UI art exactly the way she intended for it >.< I just hope I still did it justice! x3 There were bits here and there that I just couldn't use at all like her custom slider bars and fillers because every time I tried to apply them, Unity went all wonky T_T haha.
Thank you for your kind words! I haven't gotten around to checking out Burdock yet, but it's definitely on my radar as it looks absolutely gorgeous! As does the butterfly logo on your avatar btw :3
