Sometimes it's hard to tell who is speaking during dialogue (especially when there are multiple people in the scene). Maybe consider adding color to the textbox or to the text to indicate the speaker (i.e. red for the redhead, purple for the witch, etc.)

Alternatively, maybe it would work to graphically highlight the character who is speaking somehow. Like give them a subtle glow or something.

Maybe this is hard but make updates faster or give little updates every month

I don't know how possible it is with this combat system, but I'd love some kinda party mechanic. Games like these always end up feeling very lonely except for the few scenes they spend with their chosen waifu or whatever. It'd be great if there was a way to take someone with you when you go out hunting or chasing down materials. 

I have been loving this game. My suggestions involve combat. To give this more of a ccg feel, can we buy cards (perhaps with gems only) and modify our decks? Also, give the enemies a slim chance to drop a card. And perhaps we can craft cards using gems or other rare components. And one more idea, can you have the cards in our deck shuffle so we have random hands each battle? This would make combat not as predictable. 

I would think you could incorporate something like a magic book of sexual positions.  And then go on a quest to put the book back together but each page or spell you finish would unlock that for the various girls.
