i found this glitch on level 37:
put a cube through the infinite loop. when it's enters the bottom portal, press f. the cube will be under of the floor, allowing you to drop it on the buttons!

PR2 takes longer (hat factory badge)
to gamehazard:
people who want the badges to this game.
to brazuka:
i also get stepped on for no reason...
to mushyrulez:
LS1 is BETTER than LS2
lol i used kongreguide and i got the badge!
the badge description is a JOKE.
this is also one of the better point and click games, like johnny rocketfingers and the visitor, but it's a hard one.
4/5
to jimmy503:
don't rate a game because you didn't get the badge. that is not what ratings are for.
to ferbie12:
i finished it with story turned off :P. and i did it once.
the music is all right.
the last world is annoying.
but, i already got all the badges when the first came out!
3/5 for easy badges and an okay game. it's pretty overrated to me, though.
