you know, if you're going to make any of the books susceptible to being a spell book, either make the glows a little more distinct or add another feature, because some of the colors are so dark its brutal.
one more thing (for now) I suggest that if you're going to make the broom requirements scale with each black widow milestone, then please make the rewards scale as well. After all, the rarity of the golden scratch ticket seems just as near-impossible to get as the golden spinner reward.
also, the unlocks list needs some looking into. it says the next milestone for skulls from 200 is 650. I had to find out the hard way it's still every 150.
And if I didn't know better, based on the time warps and the auto pickup speed upgrades, it looks like it doesn't even take an hour for the auto pickup tool to stockpile a full set.
also, at first it seemed the blue book on the bottom shelf was the only one that glowed and had any spells. Now I got a glow from a purple one on the bottom shelf. Do any other books glow too?
