Oh well. I like the game, but I'd already played the real version once with friends, so I already knew that. It does help to play with people who've played before, as they can give you a clue of what to do and why when you're starting out. The app does provide some hints in that regard, both in the tutorial and via the ? icon (tap it during the game to get a suggestion of what to do), but they could definitely be better explained (or explained at all!)
I'm not really very good at the game yet, but I do enjoy it.
