Well each level gets progressivly harder as you get further into the game so it takes the knowledge of previous levels to solve the new one. Levels much further in the game (Around 50,60, or 70) could sometimes take weeks to solve though. 77...and I beat every one of them :D Yup...you were the one that got me into this game, and I'm one of the very few that actually stuck with it unfortunatly Trust me...No one finished it :P It took me from the time when you posted it to now to finish all 77 levels.
