Been playing since the beginning, but reviewing V0.30
As far as gameplay goes, you are combining ingredients in sets of 3 to create potions based on recipes found throughout the room. Most combine games only use 2 things, so adding one more gives more variety to the puzzles. All but a couple recipes are written in a cryptic way giving the game an enjoyable range of difficulty. One thing to note, an ingredient was renamed in an update. If you took notes on an older version and came back, they might not all line up anymore.
Moving to the art, everything looks great and moves with smooth animations. The idle animations to the potion making to the good bits, everything just looks good. The only real trade off with this is the lewd scenes are short loops and instead you are given an accompanying story. If you don't want to read, maybe skip this, if you are fine with that, the stories that come with each potion do a nice job setting the scene. The now added ability to turn pages when reading will most likely bring on longer stories and potentially more areas.
The game is set in the Harry Potter universe (or at least something like it. You can change the name of your character and school to change the stories), and if you have played other games, read the books, or seen the movies, everything will feel familiar. It doesn't add anything but some familiarity to the experience, as creating a new world with the same gameplay would be just as enjoyable. It is a welcome inclusion as the included lore works with the potion stories.
