I have played v0.4.2 and it was nice but I would comment a bit if you'd like, I hope it can help improve your game.
I like the style and while it is cartoony it has a charm to it.
The world feels quite empty, and the lack of interactions except for quests is a shame. Maybe its part of the Theme where the witch world is empty but its also not very fun as a player.
I loved that you can cast a spell and an oopsy happens but after that there are no more spells. So I hope you can incorporate more of what you learn into the world, have situations be solved using a spell you learnt or a different route, but give me the choice to feel as a powerful witch that you say that I am.
I also feel there is not enough "lewd" interactions. There were a number of situations where a small lewd scene could have been a nice pace break but alas it was only more and more text.
I think good example of what an adult game should be like is Aurelia where the story vs scene is a very good mix.
I hope this was of any help and I wish for you to have a massive success :)
