Yeah. I got to about 100 points, and there's not really any type of minigame that's enjoyable enough for me to keep getting on it. As for exploration, it is technically encouraged to read the book while you're exploring it.
Or know the book inside-out.
The minigames are cute (I like Potions!), but what's interesting me right now is unlocking more of the codices about people/places/things and reading Rowling's notes about how she came up with stuff. (her note on the Sorting Hat is really cute, and dude, read McGonagall's backstory. It's so bittersweet.)
