Can someone explain Zack and Wiki to me?

Ok. After watching some more videos, and hearing all the hype from you guys, I think I'll buy this game now (well when I get some money anyway). I already know that this will probably be considered a stupid question, but is the puzzle solving in this game anything like the old Lemmings game? That's the only point and click type thing I've ever played.
