I had never heard of it, but after I saw this thread, I downloaded it! It seems pretty cute so far. It reminds me of Pokemon Shuffle. Just, I'm concerned... The App Store page didn't say anything about in-app purchases, but when I started the game up, it mentioned them. Are in-app purchases really necessary here? What's the extent of them? I found Pokemon Shuffle to be pretty much unplayable because I hated having a limit to how much I could play at once.
