Doesn't work
Level 1 just doesn't work - the door simply snaps closed no matter where I drag it, whether I unclick on the white box, whatever. I'm using Firefox 3.5.7 on Snow Leopard, I don't know if that's the problem.
Clicking the walkthrough button just takes you to the same game on a different site, with a user-posted walkthrough toward the bottom of the page in a comment. Kind of a cop-out.
