All of you saying it's hard, it's quite easy. Just concentrate, but don't strain. Look around and take your time. I beat the whole game, and I LOVED the Hardcore Levels. They were the best ones because I BREEZED through the Normal Levels. Otherwise, the game was amazing. I hope there's another one somewhere, because I can't wait for even HARDER levels! :D
