This one of the best example of what GAMES should focus on. They are not movies.
This is a simple game, like Plants vs Zombie. U will feel joy and and frustration on every step. Every time something is going wrong, but when u came out victorious despite the odds its very gratifying.
When u can talk hours with yours buddies what u managed in the game, or how unlucky u were :), it's clear that the game has something.
This part is mostly like a filler, I will not enter in detail about the game, u read the GS review so u know what its all about in the game. I just want to say that >90% that u will not be disappointed spending 10bucks on the game. Its very important in this game to share with your friends and see their suffering too :). The frustration can turn u away easily.
