This game is quite enjoyable, animations are top notch. Just wanted to suggest a few things I havent seen mentioned yet, will be a godsend once dye ingredients are made purchasable from a shop.
Make it an option to fast travel to save pillars from the mini-map, or give the fast travel demon lady much more options to get around.
If its possible, increase the max amount of potions and flowers you can carry at one time. I don't know the limits to the game save file, so this is only a suggestion. I can manage just having to hunt around for more if i need to.
Keep up the good work!
