I think people aren't so fond of Cityblock, but I loved it! I wasn't so old back then, so for me it was really a challenge to release enough blocks and make the right path to those chips in the water so that you wouldn't run out of blocks. And then, in the end, it was so hard and I had to do it all over again a few times... which I both hated and loved... It was such a victory to finally get to the next level!
