I LOVED this game. I played it for HOURS on end (I lost a LOT of sleep, but it was definitely worth it to me). I got it on June 28, 2013 and I finished it on July 2, 2013, playing only in the evenings. The graphics are beautiful, the storyline was enchanting and it definitely is challenging. Until I got into the rhythm of the game, it seemed to go really fast (I thought). Levels 63 and 64 showed me just what fast was. Getting thru the first minute of each of those levels was EXTREMELY CHALLENGING! This one gets two thumbs up. When is the next version coming out?
