As someone already stated there's a risk of getting bored midway and that's what happened to me.
There's grind, too much of it and after the infinite quest route of getting x-materials, capturing girls, farming specific skills/objects I decided to download a full save and check what I was missing. Well, first of all there're no "Special" poses, apart the witch+2 other girls and you can have fun with 20+ characters. Nice, isn't it? Unfortunately there're basically the same poses and bodies, just few edits, breast size is the same, I mean they didn't even change that for the big tiddy monster, so to me the grind isn't worth of your time.
Story is what you see, that is someone is trying to milk you and the game ends abruptly after you defeat the last boss.
I suggest the Kagura version as it's uncensored, but again you won't see much more compared to the original game.
3/5, but without the nice art (especially the full nelson pose) I was going to give way less.
Oh in case there's a hidden cheat right at the beginning of the game. Just click around 40 times on the jar in the middle next to the witch's house for getting tons of gold, 1000 hyper pills and hyper fuck(cheat) as move.
