Tried this out because of the promotions in other games, and at first I realy disliked it. But, as you want to get to lvl 54 (or so), you get the hang of it, and now I'm kind of addicted: I realy like it, it's a refreshing 3-in-a-row game, with cool new elements.
Only thing is, I haven't had a challenge in quite some time now, and I miss them. Please, add some more
Also, on other games like this, you can earn, once a day, a special item, that can help you advance when you're stuck (like the magic trident or the cross wave). Even tho you you sometimes need to wait for days to get enough of those special items to advance, you just know you always will in the end. This way you keep playing. Perhaps that's something that can be build into this game to. Something like the Spin-to-Win in Dragon Story.
