Am I the only one that doesn't get the appeal of that game?
Based on its popularity, you might be!

It's boring, often times insanely difficult (not well play balanced), doesn't look all that great, and to me, the premise is just damn bloody stupid.
Yeah, I disagree with all of that

As far as the difficulty, perhaps it's just a game that doesn't jive with you or whatever, but the real challenge is finding the correct way to win. One or two levels were a real challenge for me, but the rest were easily beatable after a couple tries.
Anyway, I'm just psyched that new levels came out today

In terms of originality, play balancing and enjoyment, I much prefer Cut the Rope. I also quite like Zen Bound 2, but I wish it were a little bit more challenging - at least for the levels I've played so far.
Quite frankly, I don't think ANY smartphone game is really all that great. I'm still waiting for a deep, rich playing experience, and all we have so far are casual games.
