aha! i got two glitches! two that requires on slapping the slig. (note: there might be more than 2 slapping slig glitches!

)
#1: When you are at the 3rd part of 2nd screen, the one with two sligs, quickly go to the top slig when it is all the way to the left, then slap him. He falls down, similar to Alex's glitch, except with a slig now ^^
#2: At the first screen of aslik's office, when the slig is all the way to the right near the gate, slap him to make him behind the gate. A great way for more time to get the lever!
and i am invisible. that fast scrab wont get me because im in NA HAH
Edit: when did I say na hah? o_o
