Some things seen in very earlier screenshots include a completely different Diamondus set, monkeys that climb trees, different colors for the Inferno sets, a 'distort' type effect for the tubes in Labrat, and more. If a very, very early version of JJ2 is found, I can almost promise you that you'll find the Tweedle boss.
